Really helpful advice here. The “conversion” right now is as follows:
- i should have known she was this way when I married her.
- i am depriving her of who she is.
- she doesn’t want to hurt me or break up our family.
- I don’t go along with this because I have been brainwashed by society for having traditional monogamy views.
- if i don’t go along with this I am controlling her and she might as well kill herself.
-if I file for divorce she won’t except 50/50 parenting time and if that is awarded she might as well kill herself
....
One more thought: given your statements indicating you're contemplating an end to this marriage, you should absolutely be preserving evidence of these conversations, especially if they're in emails or texts, or some format that could corroborate what's being said. If these conversations are all verbal, try to record some of them and save the recordings. If not, at least write down the dates they occurred and who said what.
If it comes down to it, and you or she files for divorce, it sounds like she'll fight for custody. It's a bit of a red flag she made the comment about 50/50 custody. It could very well show she's been thinking about this already.
In my state, if you're at 50/50, I don't think either party is liable to pay the other party child support. Sounds like she knows that. A judge could still order it, but it's not automatic. Also in my state, the non-custodial parent (i.e. the parent with less than 50% parenting time) gets a default possession schedule that amounts to around 35% of the time, sometimes more, depending on how holidays and school breaks go. So if you're not going to be the primary custodial parent, you'll have to fight for 50/50, and - barring clear evidence one parent is not fit - that's a he said/she said, subjective fight. However, the fact that your wife is willing to blow up the marriage to go have an affair with some other woman is a pretty strong weight in your favor.
If this is against your values and you are not okay with it, absolutely do not allow it. And keep a record of it.
If you are already consenting for her to have a side piece and go on dates, you're going to have a much harder time in court.
It sounds like from your first post you agreed she could go meet with this person more as a friend, and there wasn't a romantic interest there, but then she blindsided you with the request to have an open marriage. I think you need to make clear - ideally in writing - that you're not okay with this, you misunderstood what she was looking for, you're not okay with an open relationship, and not consenting to it.
