How To Be A Single Parent?

I'm a single mom. My son is 11 months old. I've been searching and searching if it's okay not let him see his dad. I've blocked him and cut all my connections with him because he neglected this child. I don't want my son to feel unloved by his father but then I hate the feeling that I will let him see his dad. I just researched that a child will start to question abt his dad at 3 yrs old. And what I've planned to tell him is that.. we just didn't work out, we want different things... What scares me is.. what if he wants to meet him? And I'm sure as hell that he would want to see his dad.. And I dont want to let that happen... He doesn't love my boy in the first place... What should I do? 🥺 ##advicepls #1stimemom #firstbaby #momcommunity
