My ex boyfriend is texting my present boyfriend and asking him to leave me . I know I made a mistake of going out on a date with someone else … because in my previous relationship I used to cry 5-6 days in a week… basically I cheated on my ex and he literally called me the worst for a month and I was still calming him down and now he has started sending abusive texts to my present boyfriend … What do I do should i text my ex back or not telling him to stop doing that to my present bf ??
