In love with someone who I'm sure doesn't know that these feelings I have still exist...

This guy was my first. It was about 3-4 years ago. He seemed as though he felt the same at the time. The problem was I started to become more permiscuise. I was young and having fun. By of course that is no excuse. Sooner than later we stopped talking. But my feelings for him never changed. We started seeing other people. I soon got into a relationship. Not too sure if I'm in love with this guy. But he and I share something special. A child. He and I never see eye to eye. We live each other but were not in love. He just so happens to be close friends with my first.. Till this day I dream about him. I can't wait to go to sleep at night just so I can have those feelings again. Now I know him and I will never be together because I screwed things up and it's a bit too late. But since I'm still having these feelings, what should I do? I really need some advice.

Be honest with him and tell him how you feel. Get out of your current relationship if you are unhappy. Children can pick up on the tension between their parents and in some cases it is healthier to just break apart.
