Why do I stop liking a guy once I go out with him?

Hey, Take a read of what "A-Soldiers-Wife07" says below and it holds (what I believe) is the key to the problem ... it's not that you have a problem, but the guys ur going out with don't know yet how to keep you on ur toes or keep you interested.

I used to have similar issues (only from a male perspective) when dating. While women wouldn't dump me, they would often become frustrated for no obvious reason. Now I understand it was because I didn't keep the attraction going. In ur case, it seems like he can't keep the attraction going when he's around you (maybe he spends too much time around you or gives you whatever you want when you want, so he's no longer a challenge). When you stop seeing him, he becomes a challenge once more.

The nicest thing you could do for this guy is to tell him to look up what REALLY attracts women ... even if it hurts him now he will definately benefit from it in the long run. When I say "really attracts women" I'm not referring to the nice-guy ass kisser that women say they want and then get bored of. In my experience, women want a man who can lead a relationship to keep it fun and interesting, making them feel loved and wanted and allow them to completely express themselves (they need someone supportive). Women also want a man they know is in control of themselves and every situation, but is confident enough to allow them to grow as people.

These are my 2 cents. I hope it comes in handy :-)

I'm the exact same way. I lose interest in someone within days after I date them or start a relationship with them. I have Asperger's Disorder, so I think that's part of the reason. Other than that, I just think I haven't found the right person, or I might just never attach to anyone.
