I understand the runaway train, I get on it sometimes too.
okay...... there's always hope.
Right now, you are coming across as chasing her. You sound a bit needy & clingy & scared. That's a huge turn off to a woman. She can walk away & you're putting out vibes that you'll follow her.
You've got to put off vibes that you're walking the other direction.
Even the way you asked her to go to the movies put some guilt into it & bringing up S11. You're using the kids as a pawn. Leave them out of it.
Remind yourself every day that you're good enough all on your own to capture her heart again.
Don't invite her to anything for two - three weeks.
Next time you do invite her say
"we're going to the movies, wanna go?"
if she says yes, you say ok. if she says no, you say ok. if she says eat worms & die you say ok. got it ?
do you know if she has an appt with an attorney ?
in the meantime, you be the best you that you can be. Be polite, but not a door mat. Be helpful & pay extra attention to the kids. Give her time & space.
M 19 years, MC for 8 months, DB'd for 8 months 4 kids; 18, 15, 14, & 10 I was never meant to be a doormat. It took me years of therapy to become assertive enough to stop his abuse.
