Im so torn

Okay for starters I do suffer a little from anxiety and Depression. (I’m not sure what is relevant but I’ll just say it)

Any way me and this guy are friends ? FWB? Whatever. But he tends to push me away . Now I’m usually the one pushing people away so I would typically just drop him and move in with life.
