Your husband is being unreasonable and immature. Adoption is a very generous solution. Many couples would welcome your child with open arms.
He should accept responsibility for his actions.
Would he consider counseling?
If not, look at where you are and where you want to be. Don't stay in a volatile marriage just because. Think of yourself, and possibly that of your child, and move on with life. We all make mistakes. You can grow from this.
Sorry to hear about your partner's lack of understanding. If you are self supporting and capable to raise the child, I may want you to enlist help of woman oriented support group in your area AND or approach legal intervention if needed.
