I work in a relatively large office, open plan with lots of smaller rooms.
Long story short, there's a man, must be 10 to 15 years older than me, who annoyingly used to flirt with me. Nothing crude, just comments about my dress looking good, joking and banter. I didn't want his attention, so just smiled, changed the subject and got on with my work.
Anyway, fast forward six months, and this man has recently found out his wife is having tests for a medical condition. Since then, he's started to snap at me and be rude to me at work for no reason, whenever I tell him information I need to tell him (outcomes/information from meetings, which he then needs to deal with). I don't speak to him otherwise. For example, when I approached him to ask him to jump in on a client's Zoom meeting (at their requests and as was necessary), he said, 'oh, what do you want?'
I suspect he might be being rude/offhand with me because, now his wife might be ill, he feels guilty about his over friendliness with me, and is compensating for it. But this is not my fault! I do feel sympathy for him (and her) though.
I want to move seats at work and potentially ask someone else, if possible, to communicate with this man if possible, but I also don't want to make a fuss. I was going to make up an excuse to the bosses about wanting to 'work closer with X because I really want to work on projects XYZ'.
What do you think I should do? Only asking here in AIBU to get traction.
