I have a (lovely) neighbour. We've both lived in the block for 5years+. He was friends with my NDN who moved out last year. By all accounts they were close (both male) and would hang out in each others flats and have a few drinks and watch a movie or whatever.
I'd met both neighbours a handful of times, but I swapped numbers with the one that hasn't left because of a letting agent issue and it was nice to have someone that we could both vent to.
He seems to think we're gonna have a hanging out friendship similar to old NDN. He keeps inviting me round for "movie night" and offers to cook at his place and generally finding any excuse to just be proper friends.
I'm friendly, always reply to his texts and chat, but don't really want more. The thing is, I'm rarely at my flat. It's a great excuse, as I stay at my DMs most of the time because she has a bigger place with more space for me to WFH, and I just don't leave
I come back here for post and different clothes and to check on the place.
Anyway, I've come back and didn't tell him, and he randomly texted anyway asking when we were gonna do movie night. I left him on read for about half an hour and he's ramped up the clingy lately so messaged again saying it'd be sooo awesome to hang out. I've said I have a rotten cold and only came back to straighten the place up before inspection so probably not. He again said oh it'll still be great to see you, even if you're ill.
I sent him a video of my bathroom light flashing when its off (there's a running joke that every time I come back, something else has gone wrong) and now he's sending me hug emojis and being all sympathetic. I always moan about the flat in a joking way, like "wtf now", never in a "omggg save me way". I did not ask for hugs nor sympathy.
He's a nice bloke. Lonely I think, and socially awkward a bit (like me). I just don't want what he wants, and for all my normal directness I cannot communicate this to him. Its like kicking a puppy.
I've kind of got to the point where I either pacify him by watching a movie with him to shut him up (until next time) in which case I'm encouraging a level of friendship I don't want, or fob him off with (genuine) illness and bugger off to DMs, in which case I'm batting away texts saying "when are you back next". Please help. I don't want to hurt his feelings.
