OMG, I'm sorry, but that is really really shocking.
You cannot deny that you have put this awful man ahead of that poor boy, even on his birthday?
I actually cannot believe a mother would do that to her only child on his birthday.
Your judgement is so off.
Your compass and loyalty is so off.
That is so sad to read.
That poor little fellow, even on his birthday he is not a priority.
IMO that is absolutely emotional neglect of him.
You sound like a nice woman, but you have completely and utterly lost your way as a mother.
Your priorities are yourself and this awful man that you fancy so much.
Children do not forget.
I think you will have resentment and harsh judgement of you in the future.
Birthdays are so special to Children, especially pre teens.
Yet his needs aren't even a priority on that one day.
I really think you need to take a hard look at your priorities.
I know I am being harsh, but your choices and priorities are woeful.
