Ellynn hits it on the head. You cannot just have everything al peachy again without some pain. Suck it up.

You need to stop trying to make everyone happy... you dont want to hurt your ex's feelings by being with this other guy... wtf? You aren't seeing him anymore! It's great that you are so concerned, but that's why you are not together! What if you find this amazing guy that you are head over heels for but, ooh, "i dun wanna hurt my exy-poo..." bah... hurt away.

As for the "freind"... how many times do we see this same story happen... You cannot be friends. He is attracted to you, as you are to him. This makes a friendship impossible. Sorry. You did USE him as a rebound; making out is not something "friends" do... YOU sort of sealed the deal by being insecure and throwing yourself on him after a long relationship ended... bad idea first of all, but then don't expect him not to have feelings for you. The best thing, imo, to do now is lay everything out on the table. Tell your ex everything (if you care how he feels) and tell the friend (though I think you mentioned you had...) Just be honest in all aspects and let things unfold from there. You are trying to remedy these complex situations that you have NO CONTROL over, and you will only make things worse. I know you value this guy as a friend, but you pushed the relationship into a confusing new level. Frankly, it's not going to work now. Both of you need time alone to think and explore your wants and feelings, and you are only confusing eachother. Just be honest on all fronts.
