<human>: Provide a brief overview of the text.

I've been with my boyfriend almost 10 months. We met on OKCupid which I never expected to happen and we fell in love. He treats me like gold, he understands me better than anyone else to the point where we know what the other is thinking. He is honest and loyal and doesn't mince words, almost to a fault where he's known for being a bit too blunt lol. Any time I have an insecurity or fear, he sits and talks it out with me no matter what it is. I'm his first girlfriend after 5 years of being single or having casual flings. I was strictly single 2 years before him after a bad experience I had. 
So he's great and amazing, but I find my insecurities come out a lot, especially feeling like I'm not enough for him. He is extremely physically attractive and he tells me I'm the most beautiful girl he's dated. However if he tells me about girls checking him out I get scared. I sometimes get nervous that he's just going to realize he misses other girls and leave me. I have been worried for months and it still hasn't come true. He loves me and is my best friend. He tells me I'm his best friend too. 
I just feel I'm not good enough. I feel my boobs are too small or I'm only one girl why does he want me or my skin isn't perfect or etc. I find a new reason all the time and sometimes my insecurities come out into a heated discussion (we never yell) about something that upsets me but it shouldn't. His actions always prove how much he loves me, but if he says anything that accidentally plays into an insecurity, I internally freak out and sometimes I express it to him. 
He is my first good experience with a man, my dad was emotionally abusive and my first three boyfriends/flings hurt me. 

He deserves better than to be doubted. I am in therapy for an anxiety disorder and depression. 

Basically I just want to know how to stop being so insecure even when all logic tells me he chose me over everyone else and continues to stay with me.
<bot>: I have terrible insecurities about not being good enough for my boyfriend stemming from my anxiety, how do I get over it so I don't  end up pushing him away?
