<human>: I [25m] have been in a relationship with my GF [25f] for over a year now. She's my first ever, and I'm really inexperienced in relationships. But I'm not happy anymore, and I no longer have feelings for her. It's been like that for a while, although she hadn't noticed because I hide it from her. I want to end it, but I know she's very attached to me and she would be devastated. We work in the same research group in graduate school, so if we were to break up, we're still going to have to work together weekly. I can cope with that, but it's her I'm worried about, since her attachment to me will make the constant contact a painful experience to her.

I'll be graduating in a year, while she'll be staying for a couple more. I think I may be able to hang on in this relationship until then, even if I'm a little unhappy. Is it morally wrong to do so? Am I leading her on? I know she's in a hurry to get married and feels she's late for that, am I causing her even more suffering by delaying her more? I just can't find a happy ending to this, and it's making me depressed, especially when I think about the suffering I'll put her through.

<bot>: I want to break up with my GF, but postponing that until I graduate will make it much smoother for both of us. Is it wrong to do so?
