So I'm single, and tho I've kinda made peace with it, it still sucks. All of my friends on the other hand are in relationships. I like being supportive of them and if they have something to say that makes them happy then I'll listen, but listening them talk about their partners and the stuff they do bums me out. I'll put on a happy smile and nod along and tell them things like "good for you" but inside I'm genuinely down in the dumps. Any suggestions for what I can do about this? I dont wanna seem like I'm not supportive of them cause I am, it just sucks.
