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

So me and my boyfriend (Mike) have been going out for about 2 years now. We've had a few troubles one of these being his former friend (Caitlin). She crossed the line a few times and the friendship was ended (I'd like to add that this was a year ago and was my boyfriends decision, she upset me a few times and yeah you get the picture). 

So we're currently at different Universitys and living in diferent towns but met up on Saturday to hang out with some of our friends from our hometown. Late in the evening one of my friend shows me messages sent from Caitlin and it's basically stuff that Mike has said about me. It's pretty personal stuff, but also hurtful. It talks about how I'm never there for him when he needs me, lack of sex since we've gone to different places and well stuff like that. I was upset but I'm not an unreasonable person and the stuff he had told her was all said while they were close friends. I've talked about similar things with a close friend of mine.

Now it's been a few days and we haven't seen each other since but have texted and phoned. I'm not mad at him because he's done nothing wrong but I'm feeling very paranoid now, I'm scared of what I say and do because I feel like it's what he complained about to Caitlin. I'm being incredibly stupid but it's just stuck in my head and constantly playing on repeat.
<bot>: My boyfriend said some stuff about me, I've heard it, I'm not mad but it's all stuck in my head now.
