Most Helpful Girl
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
Most Helpful Guy
Fear of being alone, boredom and simply because they can?
