I don't know what to do. My girlfriend is going to be going away very far for college (out of the country) with a mutual friend of ours who I am already very jealous of. I am not just in regards to my relationship... This other friend and I had a conflict a few years ago since we were in a trio with a mutual friend and I think we kind of had to fight for that friend's attention? Anyways, I heard this through yet another friend, but apparently, she would intentionally hang out with people to make me jealous and at this time I was already going through A LOT of shit at home and I know she didn't know that and although we are on alright terms with her, I've never quite trusted her fully? Anyways, I have always been very jealous of her and I feel like my world is collapsing now because of the fact that I'm going to have to lose my girlfriend because of the distance and SHE IS WINNING. I know it's stupid, but I genuinely don't know how I'm going to cope once the time for them to leave hits. I know I'm already likely going to have to break up and I'm already having trouble coping with that, but genuinely, with this other friend in the equation, I'm going to lose it. This is literally the worst possible situation. This is half just a sort of vent, but does anyone have any advice with how to rationalize or cope with this?
