<human>: Give me the gist of the text in a nutshell

Hello, so I really need to get this off my chest. Let me preface this by saying that I have only ever been in 3 relationships before this relationship. They ALL cheated on me, that's how it ended. My longest term relationship was physically, emotionally, and sexually abusive and I was cheated on multiple times, so its all I really know.

I've found a wonderful boy who I was completely comfortable telling my terrible history to, he truly is awesome and generally makes me feel lovely. We have dated for 6 months. However this crushing anxiety is killing me and I'm afraid it will eventually kill this relationship. Sometimes I will get anxious over literally nothing and have a panic attack about it, this strange jealousy coupled with my insanely low self esteem isn't helping me one bit. Even if I see the tiniest bit of female interaction with him I get so jealous, which makes me feel horrible in itself because I'm not supposed to feel insecure. Like right now I just saw him comment on a Facebook post of this really cute girl that he used to have a crush on (she's much cuter than me) and it just kills me and eats me on the inside out. However all my boyfriends cheated on me with good female friends, the most recent one I had cheated on me with MY best friend. I'm not trying to make excuses, I just need help. I'm too afraid of discussing this with him because he's the kind of guy who would do anything for me and he would do something like completely stop talking to his female friends which is unrealistic and silly. Help?
