<human>: Could you distill the essence of the text into 1-3 sentences?

I've been with my girlfriend for about 6 months. we went to high school together but didn't actually become friend until college. she is without a doubt the best thing to ever happen to me. But she remains in constant contact with her ex boyfriend, and the guy she slept with while she and her ex were on and off. she knows that it bothers me, as I've told her it makes me uncomfortable, but she inists that I have nothing to worry about. the guy she slept with is still wants to get her back in bed. she told me that I have nothing to worry about, and that nothing will happen. But I've seen the conversations they have, and anytime he makes any inappropriate comment or suggestion she wouldn't tell him to stop or that she isn't interested. the only time she took my feelings about it into consideration is when she planned to sleep at his apartment when she had to go the the city early in the morning. she told me that she probably wouldn't slept in his bed with him. when she told him that she wouldn't be staying at his place she didn't tell him that it was because I had a problem with it, and that she found another place. She knows I don't like him, but won't tell him that I don't when he asks her. she told me that she when she started sleeping with him because she was in a bad place. but I'm afraid she's just keeping him around as a safety net incase things go down hill.

and just to add to it all, she has another ex who helped ruin my last relationship. he is a manipulative bastard who is the literal scum of the earth. She just had her 20th birthday and he sent her a gift. She was confused by that because she thought he hated her. But I know that he is still in love with her. She told me that she was confused but that she'd probably never see him again. they had a very intense relationship in the past. 

I don't know if I'm just being paranoid, but I'm hoping I can get some insite on that here. I love my girlfriend very much
