My boyfriend and I have been dating for a few months. Our relationship, while still new in learning about each other, connected immediately with our shared interests, emotions, sincerity, and honesty with each other.
He is a very generous, kind, and warm person. Also very personable. I'm the quieter one in the relationship and he says he understands it doesn't mean I won't have an opinion about something and to feel comfortable to speak to him. There had been times where it seems like he could be flirting with someone, such as a waitress but I knew he was being charming and it was nothing further than that.
Currently he is living with a female roommate. At first I never suspected anything between them because I live with a male roommate and in my case we are only housemates and friends. My boyfriend's roommate is an outgoing type of person and compared to me she is overly friendly. On one night my boyfriend needed another pillow and asked to borrow one of hers. As she was about to hand it him she says "this is the one I use this for" and placed the pillow between her legs. When I saw this I was a little taken back and didn't know what to think of what happened. My boyfriend laughed and said he'll just flip it over and I think I tried to laugh it off too while she was still in the room. But I was awkward about it.
The other day my boyfriend was leaving for a trip and when she realized she was going to be away when he returned she gave him a big embrace before she left for work.
I don't want to suddenly be the paranoid jealous girlfriend but I have been in past relationships where I suspected something that later turned out to be true. Having been cheated on I guess I'm worriend that it will happen again. I can't imagine my current boyfriend will cheat on me but there's nothing I can do about his roommate if she is flirting with him. Maybe its just flirting and nothing more. Or maybe I'm reading too much into it, I don't know.
But if this is something I should talk to my boyfriend about, how do I start?
