This may seem childish but I’ve had a crush on someone for a quite a long time (around a decade). I know I need to move on but been unsuccessful so far.

We haven’t seen each other for a while. He’s traveling to my city in a few weeks, and, due to some scheduling conflicts, he’s staying with me for a few days.

Thing is, I never know how to be around the dude. He’s already in a committed relationship with his boyfriend, which makes me kinda jealous TBH. Not sure how I’m gonna deal when he’s here physically in a few weeks.

Any advice on how to be around someone you never get over completely?
