What could be this Leo's intentions?

So there is this Leo guy whom I've been acquainted with for over a year now.
I've always had a crush on him but I wasn't sure if his occasional flirting was him just being friendly or if there was more. So I was a little surprised when he finally asked me out last month. Best date EVER!!! Followed by NON STOP talking the following couple of days before I decided to sleep with him and then push him away.
Yea, I have some issues with trust and maybe even a little fear of relationships.
I said a some really stupid things. And of course regretted it and asked him if we could go back to just being classmates.
He became cold and distant in the following weeks even after I apologized. So, I dropped it. Decided to stop texting him.

About a week later HE texts me. Said he's been lonely and wanted to hang out. I didn't want the focus on us so I suggested we can get together and work on an assignment for class. And while we were working on our papers in the library, he did little playful things, like lean in to look at my paper, try to tickle me or just tease me about working slower than him.
He asked me if I wasn't doing anything after we should grab something to eat. We ate, and then spent the whole rest of the day playing around!
We had fun! We were very playful. I believe we said "bye" 3 times! First, when he dropped me back off to my car after we ate and started moving his car forward while I tried to grab my things from the back seat, so I jumped back in. We drove in circles and attacking each other for a couple of hours. Second time he took me back he blocked my car in till I asked him if he wanted to keep hanging out after I drop my car off back home. We took a long walk before saying Bye again. This time he texts me AFTER he drives away, asking if he can come back.
After more playing around for a few more hours we had a pretty deep conversation. I'm pretty sure he was hoping to end the night with sex instead...
I told him that I like him but I'm not good with emotional stuff. It's rare for me to like anyone, this is all new to me. Never been in love or anything close... He was very understanding.
We shared other deep things about our abusive past. I let him do most of the talking because he was really hitting home with almost everything he said. I felt like this guy could have just finished reading my journal entries from the past month!!
He was very comforting, very kind and sensitive. A total sweet heart!
He also admitted that he'd come out

He also admitted that he'd come out of a very serious relationship (I was never sure if he was ever available for as long as I'd known him) not so long ago so I don't have to feel pressure because he's not ready for anything serious either. (...He called his ex his "dream girl." Told me that he'd wanted to marry her but she dumped him instead. He didn't bash on her though. That's a good sign.)
We didn't kiss, nothing sexual happened, he wasn't like some of the creeps I've known to take advantage of a moment when I'm vulnerable with such a sensitive subject. Such things would have only complicate or confuse things for me.
He also invited me to go to this church thing he attends every Sunday as he was driving me back home, mentioned that he'd like to introduce me to his really good friend. I said I'd think about it.
The following morning, we sat through class together, but didn't say much. He didn't even walk out of the class with me, just said "I'll see ya" while I was packing my things up. He seemed a little distant.
We haven't spoken since. Is it possible that he could have change his mind about inviting me to this church thing and never bring it up again?

What I really want to know is WHY is he spending this time with me?
I don't believe he's looking for a new friend.
But... Someone he wanted to marry, his "dream girl," What is this guy doing with ME?
He couldn't possibly be getting over someone he loved quick enough to be getting involved with me, could he?
Or could he be confused about his own feelings and the things he's doing? That might explain his distance...

I really do like him even with all this confusion. I can't remember the last time I liked someone this much.
But I don't want to be his distraction while he's healing or something. I don't want to let myself feel something only to turn up to be the fool in all of this.

Thank you, I'll definitely keep that in mind.
I never thought men would rebound with someone they know, even if it was never on a personal level. Especially with someone they'll be seeing weekly.

I'll definitely try keeping an emotional distance!

You can rebound with anybody! His pride was probably really wounded after being dumped by a girl he seemed to really love. Just be careful and have some fun with him but don't let your guard down too much. Us Leo's love to be adored so be's probably loving the full attention and laughs you're sharing with him. That being said some rebounds can become lasting relationships. So just be smart!

I read up on a few different articles about or relating to rebound relationships. They all claimed that it is possible to make something more lasting out of a rebound relationships. Most of them claimed that taking it slow would help it out.
Now, I'm wondering how something's taken slow. How long should I wait to sleep with him? Or better yet, what signs should I look for? And if I don't let it become sexual for a long time,would he keep coming around if we're still having fun? I should probably let him approach me with the whole "let's make this serious/officail" when or if ever he's ready.

I think a big part of me just wants to jump in knowing it's going to end with pain, being aware that there's a better chance it wont last long at all.
I really do adore this guy and for once I'd like to let myself feel and enjoy something even though it might not be returned or it might hurt really, really bad.
Sometimes I think I don't WANT to be smart. 😢

It's okay. You aren't THAT smart if you're seriously considering this emotional crutch crap as viable relationship material.
