@Kate thank you for taking the time to reply x
I'd be fuming. Plans were made and he's changed them without informing you. I'd ask him to reconsider, personally. He is the one who has to cancel his plans and looks after his child, not you! x
I’d be annoyed that he hadn’t discussed it with me but I do think you’re overreacting. He’s the child’s dad so does get to make decisions and they are his parents, not complete strangers. Completely understandable that you feel this way but I just think you should chill out and go and enjoy yourself. Tell him that it’s unacceptable to exclude you from the decisions again but allow it this time. Parenting is hard, pick your battles. Be grateful you have family to rely on and don’t make it harder for yourself.
I’d be livid tbh one of us would be cancelling plans I wouldn’t want someone that’s met my kid twice to be responsible for him.
I think you’re right and I’d be angry too. Your points are all valid. At this point I think I would personally say I won’t go ahead with my plans and I’ll keep the baby just so that he realises that what he’s done (thinking to leave baby) is non negotiable for you. Good luck girl x
