Sorry for the unhelpful title. I'm still reeling from a conversation my RP partner and I had earlier.

Generally speaking, things are great when it comes to RP. We both get excited about the same things and generate ideas at a similar rate. There have been some issues with it feeling like she dominates the scenes her MC is in, but we were able to get past this hurdle and it's been smooth sailing ever since.

We have many AUs planned for the series we're currently RPing post-canon. In all of them, the pairing where her MC bottoms do not have children because her MC would be too "jealous" of potentially losing some of their partner's attention.

In one of the AUs we have planned, we'd discussed the possibility of giving the partner an adult child from a previous marriage, because we'd agreed that he would want to be a father. My partner was very excited for this particular development and frequently talked about how sweet it would be that this character would get to be a protective dad. Then tonight we were talking about our plans for this AU when I mentioned the daughter in some context and my partner said, "She's lucky that [MC] will let her live."

I was confused and asked her to clarify, and got a speech about how the MC will hate the daughter and barely acknowledge her existence, but at least he won't have her killed or make his partner choose between them. WHAT????

I said it sounded like MC would barely tolerate the daughter, and my partner added, "She'll be proof of [partner's] past. A past that didn't include him."

It had already been established that the MC would go out of his way to cook, clean, and entertain for his husband's parents and siblings as a way to impress them and endear them to himself. FWIW in canon this character is a murderous sociopath, so I'm not sure how this is considered IC but not him not killing the daughter?

I said that it would probably be better to just forget about the daughter as the kind of reaction she was proposing would cause significant and lasting strain on the relationship between the two characters. She got upset, blew me off for the rest of the night, and then let me know when she went to bed.

WTF. I feel like I'm taking crazy pills for being so confused by this still. Not gonna lie, also feeling a little pissed off that this is somehow my fault for nixing the daughter character when her involvement would've done nothing. but introduce unnecessary problems.
