There are also situations where the person you have a child with may be a wonderful father or mother, but you find that you simply don't work well in a relationship together. Wouldn't it be better for a child to see their parents amicably apart and getting along well with each other for the sake of the children than for the child to see a relationship that doesn't work?
This is thinking of the kids. And you using the word "covenant" just exposes the religious backing behind your argument. I'm Pagan, marriage is not a requirement in my faith. It is an option, just like handfasting, but nothing is required except for love.
One option is to amicably part, and one option is to stay in a "relationship that doesn't work".
There is a third option. Stay together and fix the relationship. It's possible if you are both willing to forgive and change. Easy? Not at all. But possible.
We're talking about innocent children here. Children who, we assume, didn't choose their birth circumstances. We adults make choices and set it up for them. We have to give them the
best we can. Any less is not good enough.
Broken homes can be devastating to children. Some seem to survive, some never get over it. We've got to do everything we can to protect them from this.
A covenant, which has several meanings, is an agreement between two parties wherein they each promise to do something.
IMO, which you have every right to reject, if you can't commit in marriage to a man, don't have children. That way only two lives are affected.
I'm sorry this sounds harsh. I've got to be honest.
