He doesn’t want the baby

I found out a week ago that I’m pregnant (was a big surprise). I was happy but my husband was devastated to say the least. I know that kids arent something that he wants but I was hoping that he would respond a little better seeing it’s actually happening. He thinks we will lose what we have and he has been so upset since finding out. We are at a cross roads and really don’t know what to do. Over the coming weeks we will need to decide, but I’m afraid if we had to terminate that it would be a decision I would regrets forever. I would love to hear from anyone who has been in a similar circumstance. I don’t know whether he will come around to the idea and change his mind. I know that he is also upset with himself and feels selfish.
