Is it normal if i can't be myself around him?

It is such a trip. You know when you meet some people and you feel like you've known them before? That's how I feel with the guy I've been seeing and his family. When I met him, not only did I completely fell for him but I saw my future everything because we got along so well and it felt like we knew each other already and it was about time we finally meet up and be together. When I met his cousin, he even told me he felt like he knew me before and vice versa. Then I met his sister, and again, there was this connection as if we knew each other already. What he tells me about his whole family, it just feels right, it feels like we're each other's missing puzzle pieces. He came to meet my family for a little bit and he said just being in my house and with them felt like home. I honestly feel this intense chemistry with him like there's nobody else for him other than me and there's nobody else for me other than him. I knew he would love the person I am because obviously I know myself and figured that who I am is compatible with him from our same sense of humor to our taste in different things.

But what disappoints every single time is when we are together, I just can't seem to come out as myself, as the person who I know he would love; me. It's not like I'm purposely holding back who I am. It's just this natural holdback that prevents from being the person he would like which is me. I mean that's how it all started. He came to me because he liked my personality and thats how we first hit it off. Now, I just can't seem to be myself when I'm around him and it really impacts our relationship obviously. Sometimes I do things I wouldn't do and he looks turned off and in my head I'm just wth am I doing? I'm chasing him away by being someone I'm not.

This doesn't only happen with him though, it happens with different groups of people. Everyone brings out a different side of me but I know who I really am and that's when I'm by myself. And that person is the person I was when he first hit on me and now I can't seem to find her within me. Could it be because I like him so much and want to make it work that I'm just trying too hard to make it happen and lost myself? But again, its not on purpose. When I do something I would normally do as myself with him, it comes out awkward and not natural at all. I want to learn how to go back to being who I really am just naturally so he can remember why he's dating me. I don't want to lose him because he was dealing with someone else the whole time. With my ex, I was completely myself who I know my current guy would love so much. And now that I found someone compatible with, I can't be myself. Its like you can't have everything.
