I've been dating my current girlfriend for about six months. I like her a lot and all, but the conclusion I've come to is the relationship has an expiration date. At the end of the summer, I'm moving across the country for graduate school, and I know I can't do a long distance relationship.
The problem is my girlfriend is really good friends with one of my other friends, and I don't know what's going to happen in terms of friend group dynamics when we end it. Should I end it now knowing it isn't going anywhere, or should I ride it out into the summer?
If it was me I'd simply talk to her about it. Perhaps she feels the same way and you both might want to just ride it out until the end of summer?
I think talking about it together beats you using her all summer then bumming her out with a last minute pump and dump. I'd feel super guilty if I was dating someone I wasn't really into, or if I could tell it wasn't going to last.
Being super honest about how you feel seems like the gentleman move.
