I'm in the most confusing relationship I've ever been in. Help?

I think you should do what your heart tells you. And If you are here posting questions like this then i think you know that it's best to break up with him. Just tell him that you think he needs some time to get over her and it will probably be best for the both of them if they stopped dating for a while, but you love him and will be there for him, but as a friend for now.
