6 weeks pregnant. Unhappy. Considering termination

My husband does not agree with me and says he will leave me if I terminate due to mental health issues. We have an almost 2 year old and I cannot handle another child right now. This pregnancy is mentally draining me. I can’t function other than taking care of my son. I’m so unhappy, I do not want any more children. My husband is now saying he’s going to call the hospital and see if we can get a surrogate and transfer my pregnancy to her??? He actually sounds crazy at this point and told me why would you kill our unborn child if we can get a surrogate. That doesn’t even sound normal. I’m so lost I need help please I feel like I’m going crazy at this point. He’s trying to control the situation he doesn’t care whatsoever how I feel
