i have a lovely 10 month old dd. Her father has never been to see her despite living across the road. I gave up trying to get him involved in her life 3 months ago and cut all contact. A few weeks ago my exp's girlfriend contacted me via facebook. She wanted to meet me. I met her and she wanted to hear the details of an assault by him against me as the same thing has happened to her. She also wanted to know if I have slept with my ex. i got no info on why he hasn't seen his dd She has gone back to him which feels weird as I left him to see if he would get help and he ran off with her and they are back to posting happy family photos on facebook. They are back to ignoring me in the street.
I cannot move house for financial and practical reasons but I feel like I am losing my grip on reality. Is there any way I can move this situation forward. I am planning my dd's first birthday and my family have told me the adult thing to do would be to invite her father, his gf and siblings. This is so when she asks her dad when she is older where he was he can't claim I froze him out. I just feel it is opening up an old wound which never gets to heal. I would prefer to ignore them all. What would you do ?
