How should I go about in this situation
So, I have been with my girlfriend for almost 2 years and she is the love of my life, I can't picture my life without her. But recently she has been hanging around with my best frind a lot, she went away for a week to his house (he lives in another town) and now that she's back he is staying at her house even when I leave... and when I am around neither of them really talk to me, they sing and talk to each other, am I just being paranoid or does this seem wrong to anyone else?
