Based on these details, my feelings will be on trusting that you gave us all the truthful details without further questioning our answers here.
With that, my opinion is this; one or more disagreements shouldn't change the dynamics of having a baby. It's best to first calm down, be mature, and have a healthy conversation on how you're both feelings. Anger can change everything so take the time to calm down.
Ultimately, if you're going to stay together things will work out. It will only work though with mutual respect. You both sould be able to talk about your feelings, and concerns as partners anytime. However, no one, including your partner, has the right to manipulate you into making a decision you're uncomfortable with or unwilling to do. That will only lead to later regret.
To continue with my opinion. Keeping abortions, as low as, possible should always be the common goal here or there no matter what. Abortions are actually at the lowest numbers in decades because of support agencies, such as Planned Parenthood, and other family planning institutions that provide free family planning for women and/or couples like you. You both need to seek education regardless. Go for the free advice/counseling and follow a comprehensive plan now and going forward. This will Include education on adoption laws, and/or rhe economic incentives that can assist low-income mothers and fathers like you. Best to seek this education not only for now but for your future.
