How do you cope with your ex partner getting a new girlfriend? I didn't expect to feel like this but it's really floored me. I want to meet her and get along and if she's a nice person, the rational part of me says it's good and she can be a good force in my child's life. The sad part of me finds exes new effort into his relationship and playing happy families with someone new when he never made any effort whilst we were together really difficult to swallow.
