Generally when women say a guy is “too nice” they are just saying that they don’t want to date. That’s one of the “outs” considered polite by women. Ridiculous, maybe, but better than men who when they don’t want to be bothered with a woman, brush her off, sometimes, in the most awful ways...some men are very cruel to women they are not attracted to.
Yeah, I got the part that they didn’t want to date me. Except I actually think that they were being honest about the “too nice” part. Trust me, women can be cruel too. There were other women I dated who didn’t let me down nearly as easy.
