I always offer non magickal soultions first...
I understand it hurts. Been there, done that, brought back a shot glass...but the best thing to do in this situation is to let it work it self out and work on you as a person.
If you honestly believe you two are meant to be together, you will be. I don't think the dream gave you a well detailed time line, did it? Just relax and try to look at it this way...
Our souls need to learn things before we are ready for other things. While it may hurt you to see him with another woman, he needs to. He may not be ready to be yours, and not being ready will only make you miserable.
It sucks, it hurts, you probably even want to crawl into a hole and disappear from the world entirely...but it will pass and you will be ok.
