Sorry- this is a bit of a rant...and long...
FI and I have been engaged for a year and a half. Shortly after getting engaged I found out that I got into my dream grad school in Newfoundland. We moved here together in August, but due to visa/work permit issues (don't get me started on these) we thought it best if FI moved back to the States until after our wedding. When his mom and step-dad found out he would be returning home, they insisted that he live with them. FI was a bit hesitant since his mother can be a bit overbearing, but agreed so that he could save some money.
I've been planning the wedding from a distance with help from my mom, who has been wonderful. My parents said from the get-go that they would help us pay for the wedding and we're extremely grateful. FI's mom and stepdad also said that they would like to help financially and otherwise and to just let them know. FMIL will email me and ask how she can help so FI, my mom and I have asked them to help out with a few different things. We asked if they would pay for the tuxes, to which they agreed. I asked if FMIL would like to help address invitations (she is one of 11 kids and FI"s family is more than half of the guest list) and she also agreed to this. These are just a few examples.
Well, as nice as she is to me, she takes EVERYTHING out on FI. When he brought up the tuxes a few weeks ago she freaked out of him, saying she doesn't remember agreeing to that, even though we've spoken on the phone and through emails about it more than once. She now refuses to pay for anything so we have to rework out budget. When FI asked her if she was still going to help address envelopes when I get back in a few weeks she started screaming at him again, saying she didn't agree to that either. When he tells her that she did indeed agree to help out, she threatens to kick him out of the house...
The kicker is SHE STILL IS ASKING ME HOW SHE CAN HELP OUT. I don't know what to do. She's nice to me but bitches to FI about everything I suggest she help with. I've even ASKED her what she would LIKE to help with, to which she replies "whatever you want me to do, just let me know!" I don't want her to feel left out, but at the same time, she has backed out of everything she said she'd help with. I would understand if it was merely a financial thing, but it's things that don't costs money as well. I just feel bad for FI.
So what should I do? Just leave her out? It makes me feel guilty but at the same time I feel worse for FI.
