Is this typical Scorpio male behavior?

Hey guys, this post is quite long but I could really use some advice. I'm an amateur to astrology but would like to learn more, especially in regards to this situation.
So I've been dating this older Scorpio man for a little over a month. He's 27 and I'm 20. I'm also a Scorpio. He's taken me out and paid almost every time but he also likes to have low key dates where we hang out at his or my place, watch movies or TV and just talk. We have already had sex and it is amazing. After the first time we did it, he said intimacy like ours can be hard to find, which I just chuckled at because it seemed so intense.
He's said it will take a while for him to trust me and asked if I'm serious enough for him to find out and I assured him I was. He also said some things which make me wonder how deeply he feels already or if it's just general getting to know me stuff like he asked if I ever wanted to get married. I said yes and he asked what age. I said before 30 anyways but whatever happens happens. He said that he wants to whenever he finds the right person, the person he's most comfortable with.
Still, his suspicion of me drives me up the wall. Once I was texting my friend a bit because she's my best friend and we do every day and he asked who I was talking to and looked over my shoulder. When he saw it was indeed a girl, he just raised his eyes at me. He said that it's like she's my bf and I should text him a bit more. I reminded him that he has a full time job and he agreed that he is busy. Besides, I don't want to smother him? In the beginning he didn't like the fact that one of my close friends is a guy, even if he is gay. He said that he could be pretending. I laughed and said that was ridiculous because I've known him for six years. The other day he was talking about his conversations with female co-workers about Irish men and how they weren't the best in the bedroom department or even for dating. I reminded him that my ex is Irish and said he wasn't so bad, that he was consistent and I knew how he felt about me. He got so annoyed and said to not talk to him about those things and that I can't just say anything. I didn't see the big deal because it was so long ago. I've asked him about his exes before and he didn't want to discuss them, saying the past is in the past and he didn't want me thinking badly and getting jealous. I'm a very loyal person and this suspicion makes me uncomfortable. I haven't done anything to deserve it.

I may be a Scorpio as well but I hide things that I believe would make me look crazy if I were to express it.
He doesn't suffocate me though. He doesn't call me every day, normally every other day and I see him two or three times a week. He has also said to me that if he doesn't call not to think badly of it. He's also asked me to leave something to sleep in at his since I'm over there a bit (so I did) and then another day even said I could leave my toothbrush there! Every time I leave he tells me not to be a stranger, yet I've read that Scorpio men like a mystery so I don't want to seem desperate and clingy.
Basically I don't like that he's kind of treating me like a girlfriend but he doesn't trust me and some things I ask him he will say "that's for a later time". Should I still be weary of him?

all you can really do is keep being honest and straight-up with him. when he has doubts clear it up/soothe him. if he's still suspicious for no apparent reason that's his problem/insecurities, not yours.

1+.

He is feeling you out right now.

Remain strong and hold your ground through the 'interrogations' and 'tests'.

This phase will end if/when he trusts you sufficiently.

Thanks guys.
On Wednesday I met up with him to discuss his (personally, annoying) habit of calling me after work about meeting up that evening. I asked if he could let me know a day or two in advance because I have exams coming up so I'll need to focus on study and I don't like uncertainty. He said he had no problem with it, but that if both of us were free on a particular night there was no problem in just hanging out. I agreed but said we still need other stuff planned. We went to play pool and have a few cocktails... At his place he asked me to open up my heart to him, but I don't remember what I said back cause I was confused. Friday night he texted me seeing what I was up to and said he was relaxing in bed. I didn't expect to meet up, but when I asked what he was up to for the evening, he didn't reply.
Saturday evening he texted me again and we both didn't know what we were going to do that night. He said he'd let me know later what his plans were later. It got really late and I was really upset with him not remembering to text back twice in a row now. I called him and asked what he meant by letting me know of his plans later, if that included me or he just meant in general and about the day before. He was sleepy in bed again and said the night before he fell asleep on me with the texts. He asked if it was okay for him to call me tomorrow (today).
I have this bad feeling.. I guess he is testing me again but I don't get why it can't be simple. We have a great time together sans him being too intense at times. I'm very cautious but I have done a lot of non-verbal things to show I care and said I care about him. I don't know what more he wants after just one month.
