Long story short. My daughter's birthday is tomorrow. I took her out for a great day just her and I today. After dropping her off with my exes Mother because who knows where she was. My ex calls me, it's obvious she's been drinking and asks me if it's OK that she invite and introduce her boyfriend of two months to their family dinner celebration for my 6 year old daughter tonight. I could give two shits about who she's dating. It just hurts that there is another man at my daughter's birthday dinner. I'm just really feeling it right now and this sucks. Any support appreciated.
