Relationship Advice

I have been dating someone for 5 years and we have had a great relationship. We finally decided to take a break because we started feeling like we were just friends and the "spark" was gone. I found myself not being attracted to him sexually but yet I still wanted to be with him. We have always planned to marry once we completed school and now, 4 months into the break we are still on again off again, trying to decided if we should be together or not. How do I know if we are supposed to be together or not? I want to be with him and love him but i don't find myself attracted to him in that way yet I don't want to lose him. We also go to school together everyday, have all the same friends, families are friends and have this huge past that I don't want to let go of. I also met someone while we were on this break that I found to really like and be attracted to very much. Now i have found myself caught between the two, constantly listing the pros and cons of both. I can't eat, sleep, study, work and am constantly miserable. I cry everyday and am honestly lost. I have no one to talk to and everyone that I can talk to is sick of listening to me because it's been going on for so long. I am at a breaking point and am finding it hard to get out of bed everday. please help me.

You cannot expect a man to stay with you, if you are attracted to someone else. A man wants a woman who is attracted to him.
