Hi, Mrswoo,
You havegotten lots of good advice here, and I feel like you are listening to it.
Now...final step.
Block him.
Do not text to see how he is, or if he is still alive.
Do not look at his sad or nasty texts.
He is not a nice man to you, and he will keep on being not nice until you change it up.
Think of it as closing the door and bolting it.
Kick his sorry ass to the curb, yeah?
