Maybe he has something even better planned for you

Maybe he thought you wouldn't be able to go so he didn't ask to keep you from wishing you could go. He should have asked though if that is why he didn't. Still suprised you didn't find out from your sisters sooner

Well you can cruise through life without him

Ouch!

Hey, third place is still a bronze medal!

I hope you have a stepdad, uncle or someone that has stepped up to the plate. this guy is a douche

bummer op... looks like you'll be skipping the father's day gift this year, saving money that's win, right? put it towards your own cruise!

There is only one course of action for retaliation. Delete his Netflix watch list!

So, the way this is phrased, I am going to go out on a limb that you have different mothers and you live with your mother whereas they live with your father and that you're not very close to the 'favorite sisters'. Any chance they paid for the cruise? Or, if you don't get along with them and there's hostility between you, I can understand why you wouldn't have been invited if it was their family holiday - though, I do agree. My dad's been on holidays with his new family (who I'm not close with, but also haven't had any issues with) and he hasn't even mentioned it to me, so it does suck and he should've mentioned this to you regardless.

The fact that you call him ‘my biological father’ indicates there’s much more to this story than is presented here.
