Help! I need some suggestions on how to deal with this situation.
For some background, FH and I have been together for about 9 years now. It's been wonderful! His mom is actually one of the nicest, kindest, and wonderful people in my life, which is why this situation has caused such anxiety for me. The whole time FH and I dated she was nothing but kind and generous. When we got engaged and set a date, things started to change.
First, she came with us to the venue we wanted and took a tour - we all loved it! That was just about the only thing we've agreed on so far.
She would always be asking me questions about the wedding and I have been doing my best to dodge them, as I realize we have completely different visions on how this day will go - overall I'm not sure she realizes her place in all of this. Her children are quite literally the center of her world and she would do anything for them, but I am not sure she realizes that there is a whole other family involved and that decisions are being made between her son and....the bride?
Anyway, so first she would ask me questions about what I was thinking about the color palate - I told her burgundy, blush, golds, lots of greenery (it's a fall wedding). She didn't really say anything but it was clear she wasn't a fan. Not a big deal in this case. Then I would mention things like the fact that I don't want to bother with favors because people don't usually take them and she goes on about how she can do them, which I took as her wanting to help so I let that one go too. Then she had a problem with the number of people in the wedding party (6 on each side) and seemed personally offended by that decision, and that it was way too many. I can cut her daughter out if she wants?? And then she had a problem with one of the girls I wanted to have in it, etc. She also kept suggesting this VERY expensive dessert option that just isn't in the budget (she is paying for the rehearsal dinner - we are paying for the wedding with some help from my parents) - though later on she did mention that it's expensive. Again, all minor things that I'm not going to lose sleep over.
But here's the one thing I can't let go. She is deeply deeply Catholic. I think it's wonderful that she has a faith and a community that she loves so much and it makes her happy. I would never in a million years try to tell someone how they should live their lives or what they should believe or how they should marry their partner. But I don't feel like that respect of one's beliefs is being reciprocated. We broke the news to her that we won't be getting married in the Catholic church and she was upset but took it better than I thought. But then she made it clear that it was unacceptable to be married by a JP, even a practicing Catholic, and that it wasn't okay to just have "religious undertones" as was/is our intention, and that it would be disrespectful to god.
My question is, how do I establish a boundary, and *very gently and kindly let her know what her place is in all of this? How do I explain that I'm not sure of where I stand on my faith and that I wish for that to be respected, as I respect her practices and beliefs to be her own? If I don't establish a clear boundary now then I will have trouble with this for probably many years. Thank you!
