I would describe my relationship with my in-laws as okay, but we are not close, and I prefer not to see them more than I have to. I attribute this to the fact they are very religious (Catholic) and I am not. This was hard for them to accept about me, and I still don't think they accept it about their son. My in-laws raised their three kids Catholic and never missed a mass and even sent them to private Catholic school K-12th grade. My husband started losing interest in the faith around high school, but my in-laws always assumed he would come back to the church. When he and I married, they were vocal about their concerns about our lack of religion and the future we would have together.
My FIL does most of the talking about religion, and he has sent me countless emails and texts and talked to me in person about religion. He asks me why I don't consider Catholicism, why I don't think it is in the best interest of my family to be Catholic, and how sad he is that his grandchildren do not share his faith. I get that religion is important to him, and I know that he is disappointed, but he'll never let it go. And I can never feel close to them as long as they keep bringing it up. Just today my FIL was talking in a group chat between myself, DH, my MIL, my two BILs and my SIL about how he has failed at proselytizing and used DH and I and our kids as an example. I can't believe he would do that in a group chat! Has anyone else had to deal with this from their in-laws? How do you react?
