3 weeks before our sons birthday I contacted my ex and both reminded him it his sons birthday and ask if he would like to see our son as he has only seen him once during the 3 months we have been seprated ( this has been his choice as he has been depressed and didn't want his son to see him like this).
When I originally asked my ex about seeing his son he said sounds good but would get back to us. 2 weeks past and no contact at all so I contacted my ex again and asked him once again if he would like to see his son, my ex chose to ignore me but actively spoke to other friends etc so I knew he was ok.
My sons birthday come and went and not even a happy birthday message from my ex. I lied to our son ( thought I was doing the right thing) I told our son that his father called earlier during the day to wish him a happy birthday as he wouldn't get a chance later I even purchased a gift for our son and said it was from his dad.
My son birthday was a week ago a yet he still hasn't contact our son however is still actively talking to other people so I know he is still alive. Should I contact my ex and ask why he didn't bother contacting his son for his birthday or should I just leave it and act as though we don't care and see what he has to say when and if he finally does contact his son?
Any suggestions on what I should say or how to handle this would be great.
