I get really fed up when guys start fishing for compliments. If I thought you were a failure in life and all that shit, I wouldn't be with you. That goes right along with constantly putting himself down and a severe lack of confidence.
I also hate when guys can't decide what it is they like, or how it is they feel about a certain topic. They'll agree with me on something when they're talking to me, then that same topic comes up with someone else and they'll agree with whoever it is they are trying to impress now. Decide how you feel, be confident, and stick with it.
And guys who have no direction in life, or desire to succeed.
So basically, I don't like weakness.
