Overwhelmed

I don’t feel anything for this baby growing inside of me I feel bad because I know it’s ppl that wish they could just get pregnant but I really don’t want it. I have four kids from my previous marriage I started to date I met someone I thought loved me just as much as I loved him but he started handling himself differently I started to fall out of love with him more and more each day and I really don’t wanna bring a child into a broken situation. How do I explain this to them without hurting them or hurting myself by holding it in everyday I wish my body would just magically make it go away. I don’t want to have to deal with this person at minimum for the next 18years. I dont love this baby. I don’t want this baby. I just want it gone and for their dad to be out of my life 😔 edit : 9 weeks
