So I'm a 24 year old Leo female and I recent met a 27 year old cancer guy (12th July). We've been hooking up for just over a month now and it's been great. We meet up every couple of days, and when we do, I end up staying the night and pretty much half the next day. And we're up talking about so many things and the sex in incredible. He talks to be about his previous relationships, expediences, about his feelings and his aspirations. And it's great, there's no pressure, we're both pretty clear that neither of us wants anything serious right now. But I keep catching him in these moments where hes just staring, or while we're watching movie, he'll be watching me, he keeps throwing these testing questions at me to see if I listened or remembered something we spoke about earlier, he always texts, from the second I leave or he'll call randomly and we'll talk for hours. Hes mentioned a couple of times hes hasn't hooked up with anyone else or really even wanted to since we started hanging out. The other night he got a little upset I think that I didn't show him a few videos from a party I had gone to. He wasn't thrilled that I didn't want to show him things like my social media profile and etc. (Although those are just my personal rules when I'm hooking up with someone, to keep them isolated from the routine aspects of my life)
Is there something more to this or am I over thinking it? Because if there is something more happening here then I need to think this through before I end up hurting him.
