When a Leo ex wants to get back together... pursue with caution or vigor?

Would you ever get back together with an ex? A leo ex? Have you ever and were there any examples of times it actually worked out in a positive way?

He's a smart, sweet, stable yet adventurous Leo man (Cancer moon, Scorpio rising). I'm a smart, sweet, stable yet adventurous Libra gal (Aries moon, Scorpio rising). We were together for a year and a half and things got serious between us quickly. Our relationship ended because something felt off to him and he didn't feel ready to totally commit to me. Even though the topic of marriage and kids had been brought up quite a few times. I had some concerns but I was willing to work through the hard stuff, because to me there was so much more good and a strong chemistry and love we shared. He ended things anyway.

We got back together briefly a month later when he followed me to South America. He started out strong with regret for ending things and wanting to try and make it work. Then the wishy-washy behavior started happening again and I was so frustrated. Why come back if you're not ready to be with me and build something together? Why did you come back if you are still so unsure? He thought i wasn't giving him enough time and I thought I had given him plenty to think deeply and only come back when he was ready. It hurt too deeply to be in-between. It was clear he still wasn't sure, so I told him that I deserved better and felt we should part ways. He agreed.

Fast forward to two years later, we have been very slowly getting back into contact with each other. He is the one that has been initiating the texts and now phone calls. We started hanging out again and rebuilding our friendship by going on hikes, watching sea lions at the beach, and finding the best spots in town for a sunset.

Last week he set up an appointment for us to both go to a spa together and enjoy the saunas, steam rooms, and pools. He rubbed salt on my back in the steam room and then held my hand. That's when i knew that he was interested in more than just a friendship again. My heart agreed it felt the same way. Even though it's scared to get hurt again.

We spent the rest of the week going to see live music together, the sex has been the best we've ever had, and he asked for my opinions on houses he was interested in buying. He was extremely interested in areas that I would want to live in long term and what I look for in a house. I thought it was sweet he wanted my opinion and a nice dream that maybe we would make things work this time but I also made it clear that he should make his final decisions based on what he wants. Our reconnection was still so fresh and we still haven't exchanged "I love you's" this time around.

He spent some time on a long trip with his best friend and I got a text from him saying that he's gained some perspective. He feels like we are perfect for each other and that he appreciates me now more than ever before. He remembers me saying "I wish you could see us the way I do" and that now he sees it, he feels it. He told me that the way I love is one of his favorite things about me and that it's my superpower. He loves the way my mind thinks and how I approach the world. He decided to wait on buying a house for now because it's something that he wants to wait and do with me later on when we're ready. When I'm ready. He wants to date and have fun with me in the meantime and build our connection.

This all sounds fantastic... I guess my question or concern is how much of this is Leo just saying what he knows I want to hear? Or the romantic and "right" thing to say? Like I said... he's smart and he's romantic and he's a great strategist. I want to be sure this is genuine. I'm worried that because his last serious relationship (the one he had after me) was traumatic for him (ended 6 months or so ago)... that he's remembering our relationship with bright rose colored glasses on in comparison, which may burn bright and then fizzle off.

I'm looking for a passionate relationship with great chemistry, which we definitely have. But I'm interested in building something that will truly last.

Do you think things could work for us or am i blindly delusional in love?
