Met a girl, hooked up with her a few times and made her my girlfriend. Just started dating yesterday and she knows I'm leaving for college in 15 days. Today I was at her house and was being told by her parents that I should leave. Stayed around for a bit anyways and she calls up her ex boyfriend to pick up his phone charger that he had left at her house while they were still dating. Ex BF comes over, she doesn't even acknowledge that I'm dating her and she walks us both out of the house. Gives me a hug and heads back inside with ex-bf to "hang out". She told me that she has no desire for him anymore but the way they acted when he got there and the fact that she talks about him constantly tells me that she isn't actually over him. Do I end contact immediately or should I attempt to trust her? She seemed to like me a lot but I could tell she still had some feelings for her ex-bf and I'm wondering what they are doing right now. Tell me what you would do, I'm not going to blindly follow whatever is posted but I want to see how people with more relationship experience would deal with this, technically she is my first girlfriend and I have no clue how to go about this.
