To end the stress is to end the marriage?

Wanting a baby to make this marriage complete has caused me anxties and depressed. I have had two beautiful children from a previous marriage that are teenagers now and my now husband has never had children and we both want a baby the problem is that I tied my tubes at age 21.now 10 years later I meet this great man that loves me and we want a child made from our love.But now the cost of undoing the tubal is such a far away dream.
