tipper, you're doing good on breaking the pattern but it does take a long time. Your H sends you stuped txts, you're not responding, so then he escalates the content of his stupid texts to egg you into a response. It'w worked time after time, and he is expecting it will still work. Don't get pulled back in.
You've got goals, keep your eyes on the horizon.
Live your life while you are still living. Riding the trail less traveled.
