After a date or two I end up telling my life story?

If you think you are sabotaging your new relationships, you probably are. Maybe you want to put it all out on the table so the guy will know the facts and make a decision early so you don't have to invest any emotions into a relationship or maybe you're forcing the relationship into fast forward to get to the good part of a relationship...except that doesn't work. Just because you are telling a guy your lifestory, it doesn't mean you're close. It just means you unloaded everything but he has no connection with it because they're just words. If you want to get close to a guy, you have to experience things together so you need to give it time and stop pressing fast forward. If it doesn't work out, oh well, at least you didn't reveal your heart and soul to him. If you can't control talking about yourself make sure the first few dates aren't very intimate (like a movie or a concert or a group of friends) where you can't talk too much. You really can control it. Don't show all your cards too soon...keep some of yourself a mystery.

i think you like to be connected to the guy socially at a faster rate than most people. You want to get to that instant mental-connection some longer relationship's already have. Tell the guy something like: "ok now you have to start talking before i start rambling...lol"

your in a little rush; nothing wrong with that.

well yes spilling your guts could and probably is a turn off.especially if its about a past relationship.you need to stop dating and get your head straight before going any further.good luck.
