Hi there!
I went wedding dress shopping with my mom in November and bought a dress. My FMIL had previously stated, multiple times, that "she'd be there when I got my dress," etc., etc., and I would change the subject or say that my mom and I would go together just the two of us. As soon as I got my dress, I told my FMIL and said "I'm sorry you weren't there, if we hadn't found one, I was going to bring you and my BM's." She was hurt that I didn't ask her (she still makes digs about her friend's going dress shopping with their FDIL's) but I always wanted to go with just myself and my mom. My FMIL can be very over-bearing and I knew she would stress me out if she was there.
Since then, I keep trying to include her in other wedding related stuff (saying we could have a day going dress shopping for her dress, a day going accessory shopping, etc.). She went and bought a dress on her own and her shoes on her own instead. Every time she brings up ideas for the wedding, she's happy as a clam. Anytime I bring anything up, she's snarky and uninterested.
I'm not sure what else to do to help her be included in the wedding planning.
Any ideas?
