Fertility treatments so my husband can be a dad

My name is Amber, I am 31 years old and my partners name is James and he is 33 years old. We both were previously married but after separating from our spouses we found each other. It was an instant connection and we fell in love. I have children from my previous marriage and he is so great with them. However he does not have any children of his own and we would like to have a child together. I had a tubal ligation done in 2018 so in order for us to have a baby I have to either have surgery or IVF treatments. I would love to give him the gift of being a dad but I need some help in being able to afford fertility treatments.
