My parents divorced when me (16m) and my brother (19m) were 1 and 4 years old. Dad admits he cheated because he was on the road a lot and mom couldn't deal with him anymore. He worked away 3 weeks a month and would be home one week a month. So after the divorce we saw him one week a month like always.

He got married again when I was 7. I never liked his wife. Neither did my brother. She and my dad have kids together and when she had their first together baby dad and her requested the court change the custody agreement so me and my brother would spend more time with our half siblings. Mom fought it. We didn't want it either. But the judge decided we should go one weekend a month when dad wasn't there so we'd have more time with our halfs.

Dad and his wife tried to change that to a full week but were denied. A clause was added that we could stop going that extra weekend once we reached the age of 14. My brother turned 14 on the Friday we should have been going there and he didn't go. Dad's wife was pissed and fought mom about it but my brother got to say no.

When I turned 14 I made the same choice. Though I turned 14 a different week so it was something more expected when I refused to go. My dad's wife didn't like it more when I refused. She tried to swear some more at mom about it but mom wrote down the incident and said her lawyer would love to hear it so dad's wife shut up.

There were times my dad wasn't around and his wife wanted help. Once it was something broke and she wanted me or my brother to fix it, other times it was she needed something at the store and the kids were sick, babysitting was another one, and a bunch of other things. We'd always say no.

Last weekend dad's wife sent a text saying she needed me to babysit because she was called into work for the weekend and her babysitter wasn't around and nobody else could do it. I told her no. She said it was one weekend and I should be going there more to see the kids anyway. I told her not my problem. I never wanted to be there when dad wasn't. That was never my decision to go and she needed to shut up and stop bothering me.

My dad called the next night and we talked about what happened. He said his wife was upset and he wanted to know why I never go to his house for a weekend or even a few hours while he's not there, to see my half siblings. I said I didn't want to. And I told him I was tired of her trying to get me over there when I don't want to. He said me and my brother could be better about this and I could spend some time one weekend a month there. I said I'm already there the weekend he is. Dad told me it's not the point and I could go and visit my stepmom (which I always gag when people call her that) and half siblings.

I know my dad's disappointed in me but if he wanted me and my brother to be closer to his new family he should be around. Without him I don't feel like I need to. But AITA for not going when he's not there?
