I have 3 children, DD1 is 13 and her relationship with her father (Jack) is great. DS (5) and DD2 (4) have a different father (Mark), who was a part of DD1's life since she was 7 until we broke up when she was 11 at which point he stopped 'parenting' her but still loves her, buys her presents, will take her on days out with his 2.
Her 14th birthday is in 2 weeks and I was intending on inviting both BDs but Jack has kicked up a fuss about Mark being there as he has always been almost jealous that Mark also has a good relationship with her.
I know she would want both of them there, I can't ask her as it is a surprise. Jack is childish enough to refuse to go if Mark is there.
AIBU to invite both? Should I give Jack his way knowing she would be upset that Mark wasn't there too? Or should I run the risk of her dad not being there and that upsetting her? I feel I've been left in a hard place because of Jack. Any advice?
