So sorry for you, Omaha (BTW - Omaha is a pretty cool city - I fly through there for work quite a bit)..
But anyway, based on your other postings, as difficult as it may be to say, I think you are doing the right thing. After all, why try to be with someone who doesn't want to be with you? That isn't really something to hang your pride on, right? He has betrayed you in the most profound of ways, and you are doing such a good thing by just letting him go. Truly, this is his loss. You deserve SO much better, and you will find better, trust me on this one. I may not know a lot (if you've ever read my threads, it's pretty evident I know.. hah), but I do know that you deserve to be treated WAY better than you have been treated, much like all of us BS'. And someone is out there waiting to do just that.
Be strong! This, too, shall pass.
