Anyone who after just a short time of marriage is not still being sweet and showing you how great you are in it for the wrong reason. I think if he makes you feel less then great then he sucks!
If he is not completely kidding about the other women watch out. I of all people understand cold feet and flirting, but if on top of that he is not showing you that he is still excited by you. I think this guy has the same problem as me he is always looking for something better, and dose not realize what he has. I know what I have and I am working on it the looking part. I would confront him with your feelings and give him a chance if he continues then move on life is too short you don't want to waste your time with someone who is not as in love as you!
