IN LAW HELP! What would you do?

Need advice on how to handle my MIL & FIL.

We’ve been asking my in-laws to come see my two year old daughter for months. She adores them. We asked them to come for Halloween and they basically just said no, and kind of acted like they couldn’t afford it. I said we could pay for it. They dropped the convo...

Cut to today. I’m 9 weeks pregnant and we decide to go to our home town instead of them coming here because my family also lives where my in laws do and we could tell them all at once and leave our daughter with my in laws over night to have a quick get away together. (we never get this since we have no family near us). I call my MIL to tell ask her about the plan and tell her the dates and she tells me they will actually be visiting her daughter in California that weekend (weekend after Halloween- when we asked her three times to come see us) and that won’t work for them. She clearly feels bad, but I’m pissed. They will now take THREE trips to see my husband’s sister by the time they see us once. They have always favored her and it sucks.

I’ve been with my husband since I was 15 and I’m close with these people and I’m tired of biting my tongue because my husband won’t say a word. What would you do??? Say something? Keep your mouth shut?
