Quoting justanothamotha:" He is being ridiculous. I am sorry you are going through this momma. A child that age is plenty old enough ... [snip!] ... to have an abortion to have a happy relationship with him, then there isn't much hope for a happy marriage long term anyway."
I agree with her. You already know how I feel about this. It's up to you when it comes to what you want to do with your body. As far as the age thing? My son will be 3 on the 26th. I'm due on the 7th. He is crazy excited about his little sister and ready for her to come home. My parents had 6 children, all 2 years apart, and we grew up just fine.
If it wasn't the "right time" for him, he should've been wrapping it up. And arguing in front of Savannah? That's only doing more harm than good on his part. I'm rambling, but you have to do what you feel is best for you. Plain and simple.
