A guy I was dating for a couple of weeks needed space because he wanted to solve his problems at work. I respected it and gave him the space. Then I “discovered” that he and his so-called ex had gone out of town through social media. If your ex hasn't started dating another person yet, please prepare. Why would my ex give up so quickly and start dating someone else?“. She kept on being “ friends” with the guy and broke up with me a month before. Effective way to do no contact if she is dating someone else. Effective way to heal during no contact if she is with another guy; Effective way and an effective time.
