I'm so sorry you're hurting. I hope you can let go of the shame. He got himself into this predicament and it is not your fault. Regardless of what's happened in the past, what's done is done. Please do something nice for you and take good care of yourself this weekend. Ignore the idiots who are contacting you about it. Ugh. That kind of thing is just gross. They're the ones who look like a-holes, not you.
HUGS. xoxo
