So...I'm a single mother, the father has been a twunk and never met dd. So my bro has been the most reliable male figure in her life, she adores him and the feeling was mutual. However, my bro has just started dating a new girl (less than 3 months ago) and spends ALL his time with her and has seen my dd twice in said time, he's taken new gf to the places he promised my dd he would take her (and sends me the photos to show her...which I don't). He lives with my parents next door to my dd and I so she sees his car parked there and knows he is home. How do I explain to my dd why he's no longer around? He's never done a massive amount with her, taken her out maybe 3 times in all, but was always coming around to chat to her and used to see her everyday, she's devastated and cried herself to sleep tonight as I was cuddling her, as he promised he would come and see her...but gf clicked her fingers so he didn't. What do I do? AIBU to be so upset for her? I know he needs his own relationships etc..but why promise a little girl something so small and not do it! How do I get him to stop promising things he won't do / readjust her wants?
