I have had a few months off dating apps, but literally there seems to be a trend in "unmatching" . I have only unmatched where I have said to someone that I don't feel things will progress, I have met and there's no connection or where someone has said something that's uncomfortable either sexual or obviously rude.
I have been on Bumble a couple of weeks and have just been unmatched by quite a few for absolutely no obvious reason. I was meant to meet someone today and they just unmatched me.
A woman must make the first move on Bumble but can be unmatched by a man for no reason.
