From a girls pov sometimes we date guys that we don't actually have chemistry with because they're nice. Sometimes it's just that usually because the guys we do have chemistry with treat us horribly and we're trying to give someone different a shot. (Not saying girls don't have chemistry with nice guys they do but that's just 1 reason) Otherwise I'm not sure. Sometimes people just want to feel secure even if they don't have chemistry but I'm not sure
I am not sure, some people do that yes, I don't know why exactly, I also wonder the same, I mean logically it doesn't make any sense to me. May be for some people chemistry isn't everything, I don't know just saying.
