You have a raging case of SDS, or Sensitive Donkeypuke Syndrome. He won't sleep with you? Because that would be going... to far! He loves his girlfriend! But... but he loves you! Let us just snuggle. Be together. Okay, maybe a handjob... BUT NOTHING MORE! Oh, how my heart is split in twain!

I'm not going to lambaste you for allowing yourself to be The Other Woman. I have sympathy for The Other Woman. Hell, I've been The Other Woman. While The Other Woman is often seen as the villain, hers is a special kind of hell. To lurk in the shadows with your own bloody heart in your hands. It strip mines a person's self-esteem. When you're The Other Woman, you're less than human. And what makes it worse is that it's all your fault.

That said, this dude isn't screwing you because in his head he thinks that makes him a good guy. Or, at the very least, not a cheater. Whatever. I don't feel like psychoanalyzing a donkeypuke. He should seriously man up and just nail you. He might as well. The two of you should at least reap the sweetly putrescent fruit of your actions. Just because he strings you along and doesn't stick it in you doesn't mean the both of you aren't having an affair. It just means you're having a lame affair.

Of course, you need to bail on this relationship. But it sounds like he has starved you of love for so long, you are too weak to run away. Just know that he is using you in a terrible way. He gets everything he wants, plus he gets to believe the lie that so long as he's not sticking his penis in you, that he is somehow being faithful. He should write a song.

You should snap out of it, and go Shawshank Redemption on him. Muster your strength, put your heart in a padded box, then crawl through the muck and try to escape. He doesn't love you.
