help please!

Ok well, by the sounds of it, you've already answered your own question:

"I just don't wanna hurt him (current bf) and I want to get over the other guy because I know he wont give up on his girlfriend"
---

So, do that.. try get over the new(old) guy, or otherwise wait it out, tho it may be a few years... *sigh .. and yeah it is pretty unfair to your current boyfriend (try see things in his shoes), and what you would rather have him do instead.. (if you get me...)

Good luck hope it all works out... :)
