I don't believe that anyone should give up all they have. I think that if things are meant to be between two people, then both will find a way to make things work and will both be willing to give and compromise. One might compromise where they live, another might compromise their time, for example.
The only time God has asked us to forsake all is for Him. Even down to our children. VERY difficult to think of ever losing a child, or giving one up.
I would have trouble giving up a lot of things for a future spouse. Not because those things are more important than a spouse. Not one bit. In fact, I would hope that he would share in all those things with me, as my partner. I don't believe in "yours" and "mine" and all that is mine would be his. He can have my all, my 100%. All my love, my heart, my soul, my body, my possessions, etc. Everything I am and own is his and his alone.
And I would trust that he would be a wise and loving husband. My spiritual head.
There are reasons why I live where I do, and almost all of those reasons have nothing to do with me personally. They are for my children. That is why I couldn't give that up for a man, anymore than I would give up one of my children for a man. My children are the most valuable things I have in this world. Their welfare is above my own, their safety is above my own, their everything is above my own. If I married a man who had children, I would expect no less from him and his relationship with his own children.
But as the two of use joined as one, the overall dynamics would change, as now he would be the head, and I would be his support. Being that I would expect him to understand what it means to put the children above us, then I would expect that as a loving husband he takes their needs into consideration when he makes wise decisions. And if he had children of his own, I would expect ALL of our children to be treated fairly and like..... I would say equal, but equal is not always what is fair or best..... to me, there would be no distinction between mine and his and I would never think of ever asking him to put me above his children, nor would I ever think of treating his children any differently than my own. I would love them all the same.
Anyhow, I hope some of this makes sense. Sometimes I have difficulty explaining well what I mean.
