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

Ok, I'll try to keep this concise. My boyfriend and I (29M and 24F) have been together over a year. We're in love and plan to spend our lives together. This is it for us. He has a daughter from a previous marriage. They met in high school, and are 29 now...so they're obviously very close. 

I am jealous by nature. I've been trying to relax and just enjoy our relationship and believe him when he says I'm the love of his life. But jealousy creeps in. Its hard for me to grasp that people who were once so in love they wanted to have a child and spend their lives together, can see each other regularly, and possibly just have those feelings be magically gone. Its just hard to believe. 

Anyway, that's just the beginning. I've seen his phone. I have permission, but I still don't think this is right. I feel embarrassed and ridiculous and like a horrible girlfriend. But its happened a couple times-beginning early on in the relationship, and then again recently. And I regret it. But still, I saw stuff I didn't like and I need to ask for help. In both instances, he was texting friends who are women, and both conversations he is talking to them about his ex and how they got divorced because of her lack of sex drive...and how he wouldn't go his whole life sexless. I guess I just don't understand why, if he's over this relationship, is he still going on about it like this? Is their sex life still the forefront of his mind years later? Why is he even thinking of it still?

 I had a long term relationship before him, and it never occurs to me to bring up to my friends what went wrong there or anything like that...it doesn't come up in conversation because I'm over it. Is he not? 
I know I'm in the wrong for looking. I know. But I did it. And now I need advice :( Its hard enough for me to see him talk to her and stuff on a regular basis. This just makes it worse.
<bot>: I'm a crazy jealous girlfriend and my boyfriend constantly talking to his friends about his ex wife and their sex life issues is making it worse
