I have a facebook friend of 7 years. He is male and I am female. No flirting ever. Just friends who have shared our relationship troubles and chatted over the years. The last few months there have been times I have messaged him asking how he is. He has read the message and hasn't responded but messaged back a day or two later. Bit strange. Personally, i have found this a bit rude as I would just say if it wasn't convenient etc and that i would get back to the person. I only message once a week to check in on him. The reason i do this is because he has mental health issues and looks after his elderly mother. He is shrewd though and knows what he is doing. I messaged him twice this week asking if he is ok. I'm in the middle of a house move and have a boyfriend of my own and my own life but have taken time to see how he is. Basically, I feel I am being treated like shit for being a caring person now. He talkscabout himself constantly but I let him offload to me. He hasn't done this every time but it has happened more and more lately than what i would put up with from anyone else. About a handful of times. I think i have made allowances for his issues. To ignore someone who messages you out of pure friendship is not on. People who check in on you are few and far between in this world. Am i being over sensitive and unreasonable?
