I Will Not Tolerate Humiliation Just Because I’m Not Rich

You and your wife have very different values and goals and expectations. I don't see this marriage surviving. Please don't bring a baby into the mix.

of course you are wrong. just because you married a girl from wealthy background meaning you will be provided the same comfort. you should have ashamed of yourself. at least you cud have bought the ticket for yourself and her in economy. Then of her parent is providing her first class and you in economy, makes sense. If you are in true love you will accept.You seem to have no self respect for yourself. You are enjoying everything on their money and complaining when you were not the first class treatment alone in plane. Whereas you would enjoyed all royal treatment after. Landing

Sounds like your wife agrees with your Fil that you are gold digging and beneath her in class to boot, this may be just me but I'd say annul the marriage and give the F il the full hand bird. Did this a**hat or your wife give any indication they felt this way before the wedding? This just floors me, usually when a parent pays for a honeymoon it's a gift for the couple, period.

What...you didn't see this coming? You are just a gigalo in her father's eyes. He is paying for you to entertain his daughter. Your choices are to continue being her entertainment and becoming a house husband or not accepting any help from him including your wife. You either make in on your own together or you allow him to run your life- you choose and your wife must choose, too.

nope -- you did the right thing here!!!!

This couple is a perfect example of why every couple should get premarital counseling. They may be "in love" but they don't really love each other. The Dad is wrong. The daughter is wrong. The groom was wrong to marry into this situation which should have been obvious early on. They are not suited for each other at this point.

Unfortunately, you two are not on the same wavelength.
She is used to living luxuriously while you are used to living an ordinary life. This will not be good in the long run. She will always be "daddy's little girl" who gets a lot of money all the time. What will happen the day she gets pregnant and gives birth?
Are they also going to be spoiled children who will probably look down on you when they are old enough to realize that it is grandpa who has the money and not you.
Time to reevaluate your marriage before it goes that far.
Either you ask your new wife to skip all the extravagances from her father or it is separation that applies. Get a wife who is like you when it comes to finances etc. who was not born with a silver spoon in her mouth whose parents value you in a completely different way.

Your FIL overstepped his position- when he walked her down the aisle he is "giving her away" and entrusting her to another man. At that point she is not part of her fathers tribe anymore but part of the husbands tribe for lack of a better way to say it. Since she is now in another tribe she is supposed to act accordingly. If she did not want to live in poverty then she should have married into another family/tribe.
