I received a wedding invitation from my dad this morning. I didn't even know he had a girlfriend! In the past 6 years since dd1 was born I'd seen him twice per year and spoke probably once every 6/8 weeks. Then 18 months ago he stopped contacting me, when I was pregnant. I received no congratulations when baby was born, no cards at Christmas or for other children's birthdays etc. He's made no effort to make up or, heaven forbid, take time out of his own life to ask how his grandchildren are or see them and the wedding is almost 3 hours away. WIBU to not go?
