Husband with adhd and possibly depression....

So, earlier this year I decided to go back to my meds for bipolar cause I’m depressive. My husband in the other hand was just diagnosed with adhd in the past few months. We have an 11 year old boy and 8 year girl.... we’ve been struggling lately being a married couple. I brought up divorce but after talking and finding out how and what adhd is I decided to try harder and stay married. Now, 3-4 weeks later I find out that I’m 5 weeks and 6 days pregnant with baby number 3. Keep in mind that I work 4 days out of the week and he has his company but doesn’t really earn any money cause of his adhd and depression. I in the other hand have been working and trying to be stable. He in the other hand has been struggling and hasn’t applied for a job or anything at all. House needs cleaning and kids need feeding. Nothing has been done. I’m trying to be patient but idk what to do now. I’m pregnant and don’t wanna have an abortion but can I really bring another live to our family? What if it’s too much or just make baby life harder or suffer or idk make my kids go through this and now pregnant and be strong? He wants me to keep baby and I would love to but doesn’t seem very responsible for us or should I say for me to go through pregnancy. I would love to say I’ll give baby up for adoption but I don’t think I could emotionally go through that. Or my kids either.... any ideas or ways to cope with this or what do you think I should do? Thanks!!
