My girlfriend's birthday was April 3rd and mine was April 6th. We decided to go out Saturday the 6th to jointly celebrate both birthdays. Earlier my children's mother asked if I could have dinner with them for my birthday. I said yes but didn't give them a date. They understandably assumed it would be the 6th, the day of my birthday. My daughter and I have a strained relationship. She is 29 and feels I ignored her and broke dates with her while she was growing up but I was working all the time. Still she was right because I did not spend the time with i should have. I went to her when I discovered the mistake I'd made and asked if we could have the dinner on the following day, Sunday the 7th. She explained she had already switched a lot of her schedule to Sunday night to allow her to have dinner with me on Saturday. I told my girlfriend about the problem and asked her if we could cancel Saturday (my birthday) and go to dinner on Sunday. She told me it was my birthday and I could do whatever I wanted to do with it. She also said she would not have dinner with me on Sunday because she had things to do and put restrictions on us spending time together that weekend. Then on Sunday she got a call from her brother-in-law asking her to let him take her out that evening. Sunday. She told him yes. She did it without first asking me if I still wanted to go out for our birthday that day since it was now possible or telling him she already had a request from her boyfriend and had turned him down. She went out with him and told me she wouldn't explain to him what she had done in an effort to try and spend the evening with me. I believe had she told him he would have either tried to reschedule or told her to bring me along. My true belief is she was paying me back for Saturday. By the way she has broken and canceled dates with me when they interfered with something she had to do with her daughter. Every single time I told her I understood and she was doing the right thing. Every time without exception. Her daughter and niece were supposed be there too and I have a nice relationship with them. When she told me about what she was going to do I was hurt but it then got even worse when she said, after telling me she was going out with him and I wasn't invited, "at least someone is taking me out for my birthday". She refused to go out with me and instead went out with someone else then says "at least someone is taking me out for my birthday" Is this payback for breaking our date on Saturday? Am I wrong to think what she did was cruel and cold? When she found out how upset I was by the news she did nothing to attempt to rectify the situation. She continued on with her plans knowing I'd be home alone and upset while she was out celebrating her birthday with someone else. She also knew I was waiting up to hear from her that night. At 11:30 PM I got a text telling me she was just leaving the club and couldn't call when she got home and would talk to me the next day. What do I do?
