The OkC thing is not you. There are tons of guys looking just to hookup and "have fun." I've experienced this too and can relate.

In terms of your ex-fiance, could it be that he is abusing her / them too, and just not posting about it on Facebook? Or maybe he got help. Regardless, what you're going through is a terrible feeling and I'm sorry you're in pain.

I'm so sorry you're feeling this way. I am so sorry you have been treated this way. You are worth it.
