I work in a nursing home. The man who does all the maintanance is my age (early 30s) he does the training too. He messaged me a few months ago on fb to thank me as i care for his grandparent. He kind of then for 2 days straight was sending me message after message. Kind of banter and flirting ever so slightly. Everytime he saw me he would pull my hair and sometimes go red. He also told me i was ways smiling and it was lovely to see. We had some training together and all morning he was messaging saying he wanted me to be his top fire expert and stuff. Then a couple of days after training we were messaging harmless chat to eachother and he just stopped replying.
A month later im on holiday and he starts leaving comments on my fb posts. Then he goes quiet again.
I messaged him twice since april about work stuff and he replies once and then doesnt reply or open the next message. He goes red in the face when he sees me.
I didnt realise as hes never ever mentioned it to me but hes actually engaged.
I feel a little confused by him and i have training with him next week. I feel like i must have done something to make him feel odd.
I am aware he has a girlfriend now so i wont be that woman. But i think ive read his signals wrong now.
