Setting Boundaries for MLC Alien H

[In Limbo]

Just when I thought I was doing well tonight...I go downstairs and find a receipt for another movie H bought for OW. The movies were Serendipity and Love Actually (H mentioned to OW in emails that it was no coincidence they met and hit it off when they did). That, coupled with the titles of all the songs he's been putting on CDs for her has me totally deflated right now. How do you know if your MLCer is one that actually has found his soulmate and you aren't it? How do I know if H is not the one I'm meant to be with? How do I know anything right now? I know, I know...if I detach and GAL then I'll be ok either way. But that is of no comfort right now. God, this hurts.
