Why won't my ex girlfriends new boyfriend introduced himself. We've been separated for over 5yrs now and we have a daughter together. She's been living with this hew guy for a year now. Every time I ask to meet him she avoids the topic. I had the chance to finally see the guy last week and when I said hey, he avoided me and went straight inside. Wtf, ya know? I mean it would just be respectful to say hey I'm the new guy in your child's life.. I don't get it, this ever happen to anyone else?
