Vasectomy or tubes tied?

Hannah • Mommy of an angel baby, a handsome 2 year old, a beautiful 1 year old and pregnant with our surprise baby

So my so and I decided this is gonna be our last baby but he doesn’t want to get a vasectomy and idk why but I didn’t want to have to get my tubes tied unless it was absolutely necessary because I would be giving birth to two babies in an 18 month period..I don’t know what to do what did y’all decide to do? Is one easier than the other am I being selfish?
