So my FH and I are big budgeters and thrift store shippers. Both of our parents lived paycheck to paycheck when we were growing up and took out loans to keep up with the Joneses. This has become an issue with our wedding. There are certain things we cut back on due to us not seeing the need in them or finding a better deal. Both of our parents keep "gifting" us things we cut on purpose because they feel that whatever is important and feel like they're helping when they are not. My father is the biggest offender on this.
The "gift" in question right now is this. My FH bought a thrifted suit jacket in a color he wanted that does fit him perfectly,better than any other suit he owns or has worn, but we still need to find pants for him because the pants that came with the jacket are far too small. My father heard about this and is insisting that he is going to buy my FH an entirely new suit. My FH has tried to make it clear to my father that he doesn't want a new suit and we are perfectly happy letting him use the thrifted jacket he found and getting some similar enough pants that nobody will really notice or care. My father is getting increasingly angry that my FH won't just "shut up and take it" and feels that FH should just "do it because I want it and I'm paying for it". I've tried to explain to my father that we appreciate he's trying to help but we want to do this on our own and my FH doesn't like accepting gifts because he often feel liek there are strings and value judgments attached to these "gifts". My FH now doesn't want to accept any gifts from my parents anymore as he thinks it sets a bad precedent that they can get their way if they put their money into it. How do I mediate this situation before they meet up in person and start getting aggressive about it?
