In laws and future in law

Fier • USAF Veteran, wife of 16 yrs, mom to 3 kids and two angel babies

So the other day we went to my brother-in-law fiance's house to eat. We are there about 20 min when she starts complaining that her deceased husband's John Deer mower isn't working and how it costs over $1600 and she doesn't want to have to pay alot to get it fixed. But earlier she was bragging how she let my brother- in- law buy her a $13,000 dollar ring that he had to get his father to cosign for. How do you justify letting someone spend that much on a ring but your bitching about possibly having to pay to get your mower fixed. She then proceeds to talk about how much she had to pay back in student loans, her ex husband's lawyer and that her sister and her husband dropped $35,000 on their wedding but tell me her budget for their wedding was to be no more than $9,000. So while I'm listening to her throw numbers out I remind her that she went past her budget with the ring, and now the $20,000 she threw out there that her wedding now costs. She got upset when I mentioned she let herself and him go over budget and how she was also saying that her family like to eat off of crystal and China. So I say well your supposed to be getting married for you not to impress your family. Now I heard all these figures from her directly and after an hour two we leave and have been gone over and hour when my brother-in-law texts me saying can you explain the wedding/ring conversation so I told him everything we talked about he proceeds to say she thinks I don't like her( I don't know her. I've been around her 7 times now and I know more about his ex and spent more time around her than I have the new one). Then my father-in-law tries to compare cosigning for his younger adopted son's fiances to paying for my husband's truck engine when he was a teenager I tell him one was a need and the other a want. He then tells me Shannon (my husband) has always been smarter than his brother. I tell him still you cannot justify giving your younger son who was adopted everything and making your older son work for what he wanted. My brother-in-law is spoiled by both parents they gave him 3 vehicles and never made him pay for his own insurance or gas or maintain the vehicles growing up. His mom paid for his gas for the cars and my husband his father made him keep oil and gas in the truck and made him pay back the money he paid for the engine. When my husband and I got together she told us we wouldn't make it six months( in may we will be married for 16 years and Nov we have been together 20 years. But as soon as she heard her younger son gets engaged she replays to him "oh I'm getting a new daughter-in-law and grandson. My husband told me about 3 years ago she asked him if it made her a bad person because she didn't think of my daughter as her granddaughter. I met my husband when my daughter was two and was just finalizing my divorce. My brother-in-law met his fiance and her son just turned 6. I try not to let all this bother me because I'm not materialistic and don't go throwing around monetary value of the things I have my jewelry is costume mostly or sterling silver, I shop at Walmart my brand is no boundaries I am not comfortable being around someone who says they are humble and not flashy but I find it tacky throwing around figures unless someone asks me if I know any sales going on. Am I being crazy??
