Is it unreasonable to ask my husband to get a vasectomy?

My husband and I currently have two kids. Our daughter will be 3 next month and our son will be 1 in a couple of weeks. We are also expecting a baby in July.I am certain that I don't want any more children. My husband and I decided on three and I want to stop at three. He said that he doesn't want to do anything permanent and I should just go on birth control. The problem with that is I don't like birth control. I have tried different types and didn't like any of them. They all had side effects that I was not comfortable with.He has also talked about me going in and getting my tubes tied when we decide that we are done. The problem is that I already have decided that I am done. I thought we both decided that three was it. He seems to want to keep our options open. Plus, when we do decide that we are done (which I already did, I am not having anymore kids) I think he should be the one getting the procedure done.So a couple of questions here,1) What do you do when one parent is "done" but the other parent wants more kids?For what it's worth, my husband works 6 days a week and is gone from 4:30 in the morning until 7 in the evening. I already feel like I am doing it on my own. We could afford 4 kids, but I don't want anymore.2) Do you think I am being unreachable by not going on birth control? Is it unfair to ask my husband to get a vasectomy? When we do officially both decide to not have any more kids, does it make more sense for me to get my tubes tied? via /r/Parenting http://ift.tt/2mMzTMK
