Help whats happening here...am i the only one in this relationship?

Walk away. That's what your gut is telling you, and from the sounds of things it's right. He is clearly not over his ex (or exex, or exexex, or whoever), and there will be FAR more problems for you in this relationship than it's worth. It's hard to walk away from someone you've actually let in and have an emotional attachment to, but believe me it's like a drug. It's a poison that will just make more sick the longer you're "on it". You need to just cut ties and move on. And don't just jump right into another relationship. Another mistake. Take some time to do more of that soul searching, make a list of characteristics/features you want of a guy (but make it a realistic list and keep in mind there is no such thing as the perfect man!)..stuff like "hasn't had a relationship for a while" so you know he's not still having feelings for an ex. Then get out there once YOUR ready and enjoy!
