NWR-Did I mention I hate my FSIL

Wow...sounds like you have to go through alot where you live. I would hate the tension.
FSIL does not sound like a nice person. But I always say that the people that cause trouble (especially in families) are jealous of the people they try so hard to start $hit with.

I think it's horrible that you and FMIL got along and now she is cold towards you. That's hard to live around. Well Good Luck!!!
Try not to stress too much.

That stinks Why are they involving your kids?

I don't know what to say. I guess you don't have to invite anyone you don't want to.

Aw, I'm so sorry!! I feel so bad for you! Just know that you're the better person and they're just trying to make you feel bad for whatever reason! Like someone else posted, FSIL is prob jealous and just being a b*tch and your FMIL is falling into it bc of the argument. I would recommend that you find another place to live where you can separate yourself, FH, and your dear sweet children from this harmful environment. Digs are just low and there's no room for them in families. My FI daughter is a part of my family now and I make sure that she's treated the same way she would be by my relatives as if she was my own. You don't have to be bonded by blood in order to be a family and they shouldn't treat your kids any differently, it's horrible that these fully grown adults are taking it out on youngsters. How immature!! They need to grow up and realize that you and all of your children deserve their equal respect!

not to make light of your situation, but shouldn't u be studying anatomy?

just kidding.
but seriously families are crazy
