Why doesnt he feel good enough for me?

How did I guess this was going to be about a Pisces guy!? I've heard this before, some are easily intimidated. It sounds like he has some self-esteem issues. It's not your fault and if that's how he feels and doesn't make an effort to be good enough for you in his own eyes, then its a waste of time after a while. Believe me. Good luck though, I hope he gets a clue and stops over-thinking the situation!
