<human>: So it came out the other day that my boyfriend of 9 months has slept with his current  roommate in the past. They've been friends for years, and I had no problem with them being roommates, I actually really like her. But now that I've found out they've slept together, I feel really weird about the whole thing. He said it only happened once and it was a long time ago (like 6 years ago). I get that people have histories and I do think its possible to remain friends with someone you've slept with... but I just feel like that's something he should've mentioned a long time ago. We've talked about our past relationships and histories, so there was plenty of opportunity to bring it up. We've been pretty open about everything, so this just makes it feel like he was hiding it. He know that I have issues with jealousy and trust from past relationships, and him not telling me about this is really not helping. Am I wrong to feel hurt by this? Or is this me being crazy and projecting my trust issues onto him? (And as a side note, any advice to stop picturing it in my head?!)

Can you summarize the given text in a few sentences?
<bot>: Boyfriend slept with his current roommate 6 years ago, but didn't tell me until now. Feeling hurt, not sure if that's a normal reaction or if I'm crazy...
