How can I get used to this?

So I'm not a slut, but my boyfriend and his best friend dragged me into this really odd relationship. Thye both love me more than a friend and all they used to do was fight over it. It got really bad and physical, so I told them stop or I'll leave and never look back. So they got the crazy idea to have me date both at the same time. It's so strange! They each know I'm dating the other one and we hang out as a trio for the most part. I just feel so weird when they both want and stuff from me. The problem is I've become very attached to them and wouldn't know how to stop this. Is it going to end up bad or what?
