Are you living at home? Can you get out? This doesn't sound ideal...
So you have a child and you met someone online? A potential love interest? Online is hard, it's so impersonal. I've met people who told me they felt a real connection, then ghosted me. All you can do is accept they have their own life, you don't have the whole story, but you know you have value and you have to move on. Easier said than done, but we have to work at it, we have no other choice....
I would suggest if you have a harmful relationship with your parents, you try to create distance. I am the same, I talk to my dad (mum is dead) but at arms length.
