I have my tubes tied and cant have any more kids but i think my husband had a vasectomy (i pay for the health?

insurance) Having kids is not an issue for us and I feel hurt because he says he wants a vasectomy in case our relationship doesn't work out someday and he does not want anymore kids. I feel that since it isn't an issue for us WHY SHOULD I PAY FOR IT. Let him get it done with his new relationship when that happens. Am I being irrational?
