Your ex-husband is not answering your phone or returning your text messages now. He turned off his phone as soon as you called, which shows that he is a responsible person. Since you divorced, he probably didn't want to divorce at that time. You forced him to divorce, so he is very angry with you now, or he doesn't have any feelings for you. Naturally, he doesn't want to suggest calling or returning your text messages. This kind of mood is normal. In addition, I think the most important thing is that he doesn't want you to contact him again, that is, he doesn't want you to ruin his mood. He ruined her present family and yours. I feel responsible for both of you.
