Selfish?

Sussett

My boyfriend has two kids from a previous marriage. I'd never been sure I even wanted kids until I found out about my little Blueberry. I'm totally in love but I don't want morr children after this. Three is more than enough for me, so I plan on talking to my doctor this week about getting my tubes tied.

My SO isn't happy about it. He wants one more after this one. I was honest about not wanting to have children in the first place. He finally agreed to support my decision even though he doesn't agree, but he keeps referencing our "next" child.

Am I really being that unreasonable or selfish?
