Is it normal to feel so insecure and sad with the person you love?

I love my bf and he just recently expressed his feelings to me of how special I am to him but for some reason I still feel wrthless or not good enough for him. I think its cause of how much I love him so it just scares me in different ways. When he expressed his feelings, we were pretty drunk but we still knew what was going on. I remember everything, we were just more emotional about it.

I feel like okay after so many times questioning him plus a little bit of liquid courage, he just blew up and expressed his feelings of how Im his girl and Im his target to make happy or to be in a long-term relationship, if its been about a yr. I feel like if this was a few months then okay. After that, he really did show me that I was a priority. I was so happy because for the first time after forever, he was acting like a bf and not like just the guy Im seeing.

Its been a few days now and yeah I feel good about everything compared to before. But one of the things he mentioned I think while we were drunk was how he's just the type of guy who likes his space out of the blue and he said how I take that as he doesn't like me. The cab driver who was around our age jumped in and agreed that some guys like their space and having their girl around, too but he also told my dude that he can tell how much I cared for him and he needs to appreciate it more which he did and has been. But there's just something in me that feels he doesn't love me like I love him and I have pretty good judgement.

It sucks when I look at him, I feel like he's my world. But when I see him looking at me, its like Im just his girl but not his "baby." I wish he was crazy about me like my ex was. I wish he felt what I feel for him. Maybe he does but he has his own way of showing it.

At the same time, I feel like now that he knows how much I love him, he's scared of breaking my heart and leaving me. Its like he's giving me a chance cause he sees potential but deep inside he doesn't need me and can find someone better. It hurts and after that conversation, I really thought I was going to feel better for a long time but Im already having doubts because its true...he can do better than me.

Im scared tho to confront him again because he will explode or quietly just end it cause that last convo was a big one and a turn around. If he hears something from me soon again, he'll definitely be done. He said that in the convo that we should just go our separate ways but eventually we expressed our feelings and made up. I don't wanna go with the flow like before after how good everythings been going so idk...I should just chill but when you love someone you wanna hear from them all the time.
