<human>: I don't seem to trust women. I've had bad experiences before which have shaken my confidence and insecurity and I'm trying to get over it.

Enter my new girlfriend of 4 months-ish. (We're 23).

She's admitted to cheating on practically every boyfriend she's had. She cheated on her LTR 3-year boyfriend with 8 other men. She swears she's changed and thinks the world of me.

Problem is, I have trust issues. She hangs out with her 3-year relationship probably once a week. She's admitted that he would probably go back out with her in a heartbeat, but that they were meant to be just friends and nothing more (the cheating was a lack of sexual chemistry). I believe her. She says their families are close and he's kind of part of the family, but there is no way in hell she'd ever do anything with him again.

She insists that I fulfill all of her needs etc. etc. and it makes me feel great, but I still can't shake this awfully jealous feeling like I'm just WAITING for it to happen. It's eating me up inside. I've talked to her about it before but the uncomfortable feelings come back when she hangs out with this ex of hers (and other male friends).

Can you provide a brief overview of the text?
<bot>: Girlfriend has a history of cheating that has me constantly worrying... besides that, she's an awesome person and we're awesome together.
