FH's family members is not attending to the wedding. Not even parents.

My FH's family live in another state. His parents wanted to come but they have health issues and they cannot flight. His dad has heart problems and his mom other health issues. And family members work, don't have money etc... His sister is 6 months pregnant so she cannot come either. The only one that was coming was his brother with a friend. But I just found out that he can't come either!!!!!! Because he cannot find anyone to come with him and he doesn't want to be all by himself. Because there will be only people from my family and we will be busy to keep him company that day. He said he doesn't want to come by himself to feel lonely at the wedding. I'm just a little mad because it seems like they don't care. I don't think it's a nice thing to do and I'm sure my FH feels bad, even if he doesn't show it. And his brother was going to be the best man too. I just think his family is not very nice to us. And what's the point of gifts? What really counts is their presence that day.
