Is it normal to be with someone cause they make you feel this comfortable?

It's probably not the comfortable you think. You probably think comfortable being yourself, and they won't judge you for it. You probably think comfortable that your flaws don't get in the way of them loving you. Well my "comfortable" is a little odd. With my bf right now, one of the things I just hate about being with him is how he makes me feel uncomfortable and awkward when Im just being me. I can't fully be all out there cause hell look at me weird, he'll judge me, he'll make it obvious he doesn't like something I did, etc. But all of that Im used to since a kid. I grew up not being accepted by my older siblings and at school. So I got so used to it that idk how it feels to be accepted. When I do bump into someone who does accept me, which is soooo rare, I feel like its not real and eventually I get awkward and uncomfortable. This is why I somehow feel comfortable with my bf...because he makes me feel my normal by the way he's usually not accepting of me. He reminds me of my siblings, by how hell make fun of me. I feel like I am myself around him since this is the only person I know within me; not being accepted. It's like I hate it but ironically I feel so secure with him because he makes me feel insecure and that who IVe been my whole life. If I were to date someone who is accepting of me and loves me so much, I'll feel like not myself and as if that guy is a stranger. I know this is bad cause why would you wanna be with someone who makes you feel insecure? But in my case, he reminds me of home. He is still with me regardless so he does I guess look through my flaws but sometimes I wish I can get rid of him but I'm so comfortable w him.
