Hugs to you!

I would be excited and accept. (I would never send him a request myself, but if he would send one to me, it would feel like I am not the one who started the boundary crossing). However, I would then be 1) self-conscious about what he would think of my profile (but probably mostly excited about him seeing more of my life), 2) feel self-conscious in his place if his posts or picture would be awkward in my eyes (the overly critical issue is something I hope I can do away with or make progress on at least).
