Falling out of love

This is my first time asking for help. I don't really know where to start. And bear with me because this is going to be long. I've been dating this guy for a little over two years. I had fallen in love with him long before we started dating. He was a dream come true for me, honestly. He had every trait I had hoped for and more. He would always surprise me with these beautiful notes, and dates. He was beyond perfect. But there was always just something there that felt like a riff between us. I have no idea what it is. It pushes me away. Just a little. But it's been enough. A year ago I left for college 1500 miles away from him. During that time my best friend dropped me out of her life and I was devastated and felt utterly alone. So once the year ended I left the university and decided to attend the one that is closest to where he lives. However, during my time away at college, something happened to me. I felt even more disconnected with my boyfriend. One day recently after my return, I felt an overwhelming burst of confusion. I was pummeled with waves of depression and fear for my future.Conveniently, a deadbeat ex of mine made contact with me. In my breakdown (as if that is any excuse) I slept with my ex. And just to be clear, he was my "ex" for a reason. Many, in fact. This guy is a jobless, hopeless, smoking jerk who still lives with his parents. I don't know how, but that one night sparked something. I started seeing him almost nightly and now I've found myself somehow falling in love with him. I'm no sure how. He has every trait I want to run frind. yet want to leave my man for him. What do I do?

They say you're more attracted to what your not looking for then what you are looking for. My opinion is, I would drop your ex though. He already had a chance in your life & he blew it. It's not very fair for your boyfriend now when all he's ever been is good to you.
