Oh my gosh. What a year. I can't make your decision for you, but I can ask you a question.
I too had an unplanned pregnancy. I too was threatened, blackmailed, yelled at, you name it to have an abortion. I didn't have one.
And here is my reason why: I knew that I could never, NEVER stay married to someone that had bullied me into such a huge decision. My husband had left my team, and so I was now my own team captain. Our marriage ended as soon as I became pregnant.
So, just putting aside all the financial stuff (if you can) for a moment - would you still want to stay married to a man that has treated you this way, refused to engage in civil conversation about the matter, and bullied you to do something against your will?
If not, then you can put aside concerns about your marriage, and make this decision just for yourself. It's ok. You can do it on your own.
