Please don’t judge you don’t know unless you’re in this position

My husband and I have been on the rocks for a while now like 2 years ( we have 2 kids together) and no amount of communication seem to help. I should have been on birth control I’ll start there and now I just found out I’m pregnant but I don’t feel the need to tell him or want to continue to pregnancy. Is this wrong of me? I have so much responsibility already with 3 of my boys that he doesn’t seem to partake in and having another child in this equation isn’t the answer for US unfortunately I literally just took a test last night because my period was due yesterday so I’m very early . My whole thought process yesterday was I just can’t I can’t handle another pregnancy alone and unsupported, I can’t continue to work full time and take care of all 3 of my boys without the help of a partner and I just can’t focus on my Master Degree in Nursing with all this going on by myself. I say by myself because my husband wants all these kids but isn’t there when I need him emotionally or physically or during labor he doesn’t care to be present. So I feel if I’m doing all of this alone in a marriage do I still tell him like am I obligated to or just carry on and handle my own business? I plan to contact my OB Monday (tomorrow).
