My dad lives about 3 hours drive away from us and my young children are growing and we don't see each other much due to the distance. A few years ago he said he wanted to do more things with my 3 boys so we have done a few things and I set it up and buy tickets for him and my stepmother. The first trip they both came and it worked out. The second trip we bought tickets and were going to drive a few hours away. My stepmother cancelled and my dad only came, wasted ticket oh well. Our next trip my dad wanted to go out of state across the country where we could see distant relatives I've never met and do some fun activities. I had some airline credit and could put down additional money for pretty reasonable tickets so I planned our trip that is in 2 weeks and told him on January 1 of this year. He agreed to it and said he would try to meet on those days which would be our kids spring break. I called today and reminded him about it because I was also calling to invite him for something else for the kids. He told me he will not be going and it's because he wants to go to my sister's graduation from college (she's 46) from some online nursing school out of state. He can't afford both trips so he wants to do that one instead. He offered to tell me that he didn't call me ( he's very retired) because he's been so busy. So now I can't get refunds on the tickets and my children still want to do a trip. I didn't get angry on the phone I just said okay and politely ended the call. I am livid but feel like for my kids sake I still have to do the trip and don't want to flash on my dad but feel like he did us wrong. What's your thoughts?
