Let him own his own baggage. If he cannot see how he's got a messed up value system that costs him relationships -- his prob. He might consider your feelings for a millisecond but in the end his wants trump yours. So screw ya. And when he screws you, he still expects to get a smiley face sticker from you for his deigning to think of you for a tiny millisecond? Wow!
You own your own baggage and get thee OUT of this nonsense. You deserve better.
I am so sorry you are enduring this.
But hard, swift, fast, clean. CHOP.
That gets YOU to the healing place faster than dragging it on. Breaking up sucks for a while before it gets better. But never ending
suckage? That's worse!
