So I have this girl I’ve been friends with since early high school, we had a brief time where we dated but decided it wasn’t right at the same so we just decided to be friends, fast foward like 6 years we’ve stayed friends just not super close, well she was in a long time committed relationship till about 2 months ago after they broke up we started talking and seeing each other more often and she told me about a month ago that she did like me but wanted to some to figure herself out again before we officially started talking which I was fine with and understood where she was coming from, so we’ve been hanging out quite a bit over the past month or so and I thought everything was going great. Well I had to leave for a work trip for about a week which I let her know about ahead of time she said she would miss me and we’d hang out after I got back so I left thinking everything was great. Well I just found out yesterday that she’s been spending a lot of time with another guy, going out to the bar, and crashing on his couch because her ex-bf kicked her out of his apartment and she doesn’t wanna live back at home. Which I offered for her to come live with me after I got a new apartment, I don’t have a place for her to stay with me cause i moved back home for a few months while I got my business going. I just can’t figure out if she’s fooling around with him while I’m gone and just using me when I’m home or what. She tells me that I’m the only guy she’s interested in for a relationship and that the other guy is purely a platonic friend but I’ve just got a bad feeling more is happening that she’s not telling me.
