So, my FMIL brought up to my FH that she wants a Mother/Son spotlight dance... FH said he doesn't care one way or the other, but I have honestly never seen this done at a wedding and find it odd... I guess I just assumed he would dance with his mother later in the evening, just not as a spotlight dance. Aside from me thinking it to be odd, I also think it could/will take up just a lot of time and add to the "boring" part of the wedding; we are not being very traditional and want a fun and upbeat atmosphere. I feel like more spotlight dances would just be... blah. Is that bad of me? I didn't even know they were a thing until she asked.
Re: Mother/Son Dance
Honestly, all three spotlight dances combined take less than 15 minutes. The only time I ever roll my eyes is when people try to do choreographed stuff. Otherwise, it’s normal and not boring.
Let your FMIL have these 3-4 minutes. She raised the man you love and it’s obviously important to her.
Sounds like you have a lot of animosity toward your FMIL. Maybe it's warranted, maybe it's not, but it sounds like she's in your lives (or at least in your FI's life). It also sounds like you want to say no just to be spiteful, which is in all likelihood only going to make the relationship with her worse.
If your FI wants to do it, do it. Consider it a moment for you to go to the bathroom or get a drink.
Unfortunately (for you) at every wedding I've attended with dancing, if the bride danced with her dad, the groom had a spotlight dance with his mom. That goes back as far as at least the first wedding I attended that had dancing and that was back in 1994. That's over two decades telling me (and YOU) that a mother/son dance is common.
Look - I don't doubt that your MIL to be can be a pain. But PLEASE do not use your wedding as a punishment/reward system. It will hurt your FMIL but more importantly, it can hurt your FI/DH and the entire relationship that you have with one another.
One friend has a particularly stressful relationship with her MIL. The song her MIL picked for the mother/son dance was TERRIBLE. She used it as an excuse to get out of the way.
Here's what I would do:
-MIL gets to pick the song. She and your FI get a mother/son dance
-MIL does not get to interact with the DJ for anything else if she's not paying.
-You don't have to participate in their dance. If anything, that can be a time that you scoot away to do something else. You can even create a little white lie and say that someone just asked you an important question / you need something, etc.
-When the dance is over, you go back to do your thing. Your FMIL is happy, you smile and all of you move on.
If you use your wedding as a platform for your control it's not going to go well. And trust that someone who is trying to manipulate you through other situations won't stop at the wedding day. However if you smile at her, hug her and know that she has this moment, it's all going to reflect far better on you than the current proposal you have out now.
In the meantime, pick your battles. Remember - the wedding isn't the end but the beginning. I've had my share of issues with my MIL but now we're on great terms and I love the grandmother she is to my kids.
Don't throw the baby out with the bathwater.
It sounds like you want to use your "power" over the situation to deny her this moment. Because you can. Because she's awful. I get the temptation to do that. I really, REALLY do. But don't do it. It's not right and you should take the high road. Be the adult here, even when she probably hasn't been.
Once y'all are your own family (and maybe you have a family), you will have LOTS more power over situations that you can exercise. Holidays, grandchildren, vacations.
She raised the man you love and she wants 3-4 minutes to "see him off" (same as your dad probably wants with you). Give it to her. What goes around and all that....imagine if your future kids marry someone who denies this moment to you or your FI.
