Feeling defeated :(

Me (24) and this guy (27) have been talking for almost 4 months now. When we first started texting it started off as both of us talking about how we were done with relationships and telling each other about our awful experiences with dating.. now almost 4 months later it kinda developed into us texting and talking on the phone every single day, we see each other every week, stay the night together, we’ve met some of each others friends, and I’ve met his mom (he’s supposed to meet my parents this week). He’s not a perfect man, but he’s a trying one and he shows me through his actions that the effort is there and he’s investing in me. He plans the majority of our date nights and he pays for pretty much everything. The only thing I’m left feeling unsatisfied about is the emotional connection🙁 I personally still don’t feel like I’m ready to drop the L word, but I wish he expressed his emotions a little more whether it’s just an “I miss you” or something! I will say I’ve never been in a healthy relationship so I do tend to question what is okay and what is not okay still.. so do guys take longer to express emotions? He’s tried to explain to me that he’s been hurt in the past and although he’s healed from it, he feels that it takes longer for him to let his guard down. Does it mean that I’m not the woman for him if it’s been almost 4 months and he’s still not really expressing emotions much?

EDIT: After sleeping on it, maybe I do need to see a therapist.. I truly don’t want to mess this up with him because I know in my heart he’s a great man.. my brain just likes to self sabotage. I feel like maybe the root issue is that I don’t trust myself enough to know what is okay and not okay to accept in a relationship so I feel panicky if I have an idea in my head that isn’t being met and that’s not fair to him.
