Siblings not going

I’m from Sweden and my fiancé is American. We live in the US. We got engaged in Greece and later decided that would be our wedding destination. Part of the reason being it is only a 2-3 hour flight for my family in Sweden.
I sent my family members a message in December, so about 7 months ahead. In Sweden both my siblings would be able to take time off since they have 6-8 weeks paid vacation.
My dad is in his 80s and has had some health issues lately. He wants to go but he wouldn’t be able to travel by himself. My parents are divorced and my mom is going to the wedding. My brother told my mom that his work got notice that their branch is no longer going to exist. However, his agreement with them makes it so he would still get paid until he finds a new job. My sister signed her dog up to be a search and rescue dog, so she is going through training with it this year. That is the reason she says she can’t make it. My brother is blaming the uncertainty of his job. (Even though it sounds like he will definitely be taken care of). In a perfect world, either my brother or sister would have cared enough to not only make it to the wedding, but also travelled there with my dad. I’ve lived in the US for about 25 years and I can count on one hand how many phone calls I’ve gotten from my siblings. Each time it has been about a health concern for mom or dad. I used to call them but after a while I realized how one sided it was, so I stopped. After that, they never called. Last summer, my two kids and I traveled to Sweden. I had arranged with my brother 6 months ahead that we would stay with him and his family for a few days after flying in. He would pick us up from the airport. I booked tickets to the closest airport to where he lives which is hours away from the rest of the family. Less than a week prior to us flying out he sends me a message on messenger in the middle of the night (because of time difference) saying that unfortunately he can’t pick us up because he has to work. After I call him I also find out that his wife won’t be able to get us from the airport and we also can’t stay at their house since he has to work. So I have to get a hotel for us and then next morning get on a 4 hour train ride to where my dad lives. Not just extremely inconvenient, but also very hurtful. I am very hurt that they are not putting any effort into going to the wedding. It makes me feel (again) like they just don’t care about me. I’m to the point that I don’t know if I will ever reach out to them again after this. I don’t want to “convince” them to go, because I don’t really even want them there now that I understand they don’t care about being there. But how do I get over the hurt?
