The moment you have to recruit people to put another person down, in order to convince someone of your value is the day you dishonor your children, your parents and your God. If someone doesn't see your worth the problem is them, not people outside your relationship.
There are many types of marriage relationships and all of them can work, but none is sadder than the one that doesn't represent peace in your heart.
Temptation goes both ways. Sometimes, you can be tempted to live a half life because it pleases someone else. Don't ever live in such a way that your heart splits into two souls. You might find yourself sinning for the rest of your life because you don't want to really be in that situation, but you don't want to hurt the kids. That is a hell that your children will pick up on soon enough. Staying for the kids is possible, but it takes two people to agree that choice is their lifestyle, not one. Otherwise, you hold another person captive because of your fear of stating the obvious-- you are not in love with them.
If they keep coming back to you, it isn't love. It is because you made yourself and easy option. The moment the thing they truly want becomes less difficult to obtain is when you will realize that your worth was on sale.
