Stood my ground, offered to each of them, very kindly, if this is not what you can handle, no problem. You can leave at any time. I had the convo again with my current GF. Day one, when we started dating, no marriage and no lawyers. Pretty simple. Not sure how it can be misconstrued in any way.
TBH, at my age, I really do not care if any of them stay or go. I never had this much clarity until after my divorce and subsequent annulment. Simple fact is, I am getting older, and I do not want to have to start over, nor have any State or person have control over me. Marriage is control, it's not an equal partnership. I can honestly say, I hated being married. I didn't like what mine was ours, and vice-versa. I do not want anything from any one else, so I never understood why I should have to be forced to share my fruits. If I want to, sure, but as soon as you are married, every penny you earn is half the other persons. Unfair in every way. Would I miss them (or her) if they go, sure, but I'd miss my financial security more. Females can be replaced easily; usually with a hotter and younger model. Finances and assets, not so much.
