Someone I know through my local community centre/group and see quite regularly asked me to go on a date (out of the blue). I politely and respectfully turned down the offer. He seemed OK and said he hopes our interactions will not change. I assured him things will be the same. However, he has changed towards me. I bumped into him today, as normal, I greeted him, he said hello (with no eye contact) and then turned his head the other way. I was going to stop by and have a chat as we normally do, but, I just kind of continued walking.
A similar incident happened yesterday, when I walked into the room, he pretended he didn't see me, again thankfully I was talking to someone so it wasn't too awkward for me to be blanked.
I don't think he had strong feelings for me as we've only started talking about 6 weeks ago. I've given him no indication that I'm romantically interested in him. I feel quite upset because we got on so well and was hoping we can be friends.
I feel he's been unreasonable and I don't know how I should proceed? Not interested in playing games and at the same time, I don't want to be ignored.
