OP here we are back from our trip

. While we wanted to wait to deal with this DH received an email from the groomsman2 Wednesday. So I'll back up and describe the wedding party.
Best man - single, construction worker still lives at home.
Groomsman 1-Father of the groom. Almost retired, owns a business for a long time. Financially they are very comfortable. Wife never worked and they have nice home and a nice vacation home.
Groomsman 2- teacher, got married a couple of years ago.
Groom- they have a 4 year old daughter together they been together almost 10 years. Works at dad company.
DH and I are in our late 20's so are all the others give or take 1-2 years (except for grooms father). We have no kids we have been married for 8 years. We did have a very nice wedding that my dad paid for it. My bachelorette weekend we had it at a spa and it was nowhere near the cost of this trip. DH just went out with his friends for a night. Because my dad offer to pay for our wedding and our families and friends don't live near each other we had the wedding in my hometown which meant most people had to fly there. I didn't think it was fair that my dad would had to pay the whole wedding plus airfare, hotel, etc. Although his offer to pay didn't come with any strings attached or budget was set. I still try to keep cost reasonable because I feel weird spending other people's money.
Ok back to the story. Groomsman #2 told DH that he can't afford that since they are trying to buy a house and it is just too much. He asked what he thought about it. So after a few emails back and forth DH and groomsman #2 send and email together. Saying that they appreciate the invite, but they will not be going on the trip and that each of them are willing to contribute $200 towards the party and that they hope they have a good trip. We still haven't heard back from them and I don't expect to since they really didn't leave them another option than to take the $400 or nothing.
Honestly think most people have just unreasonable expectations and mostly they come because they are immature and have no other responsibilities. Unlike many of our peers we have owned our house for 8 years, and while we do have a nice amount of money to do whatever we want because we don't have kids we don't like just to blow it. Most of my single friends with good jobs spend their money in stupid things and are not worried about saving for retirement or saving at all and most likely won't put much if any away until they get married and start understanding responsibilities. The truth is it doesn't matter how much you make because if you are not responsible you will end up in the same place regardless of income.
