What makes a guy very friendly chatty interested attracted and flirtatious for a few weeks and then suddenly back off?

Often with the human species it's called "the chase!" That's the fun part of any relationship. The flirting, trying to impress, etc., and once that person has your total attention and interest in them, they may back off. You didn't really explain your situation as to whether you were going out together on a permanent basis. If you are and he's doing this, he may just be comfortable with you. Women should always keep a guy guessing and never be too accommodating. Keep going out with your girlfriends, and if you aren't going out with this guy, then date other guys and keep him on his toes. Good luck Marcy Answer This is exactly what I am going through right now, but I want to know how long the "backing off" is gonna last. We've already made contact a few times since he strated this, but it's not like how we used to talk evry day. I keep wondering what I did wrong... But I do not call him, except to return phone calls or text messages, and I DO NOT do it immediately.. When does it return to normal? He always says that he can't find a single thing that he doesn't like about me... Answer I guess it's a mixture of 'the chase' and also uncertainty on the guys part. I wish they (guys) would just say 'no thanks' and go away if they're not interested - sadly, they will string us along because they're not sure and want to keep the door open. I posted the original question and have also had the 'there is so much about you that's great' statement too. My strategy is to leave well alone and I'm working on the assumption that if he's that interested he'll be back. It's tough when you like someone and they appear to like you too especially with all the 'baggage' so many of us carry from previous marriages/relationships. The secret is .... DON'T WAIT! If he's playing these games be serious and start going out with friends, having fun and if you meet a nice guy then see where it leads. Life is too short to lose time on someone playing games. The poster that said, "I wish guys would just say no thanks" has hit the nail on the head. The problem with this theory is the fact most men don't like confrontations and at early ages are basically into themselves and don't care about who they are hurting. It's simple. If a guy truly loves you they are there. If they don't love you or want to be kids in a candy store then let them go. It hurts and there is no doubting that, but if you hang around you enable their behavior.
