I'm guessing you keep posting because you're desperate to talk about it but you know full well you will never chuck this guy.
Your lifestyle is unhealthy, you don't eat well and you stay up all night, you have an incredibly toxic relationship with this guy (both of you are bad for each other I think) and you have what sound like toxic or no relationship with most of your family members. You also don't seem to have any close friendships.
Basically you need to start fresh. You need to find a way to break this poisonous co dependence with this guy, start looking after yourself and focus only on any healthy relationships you do have in your life. Maybe take your baby to some baby groups, or reach out on a mum and baby networking app rather than one like Yubo which isn't going to get you the kind of friendships which will help you to become more stable.
You rarely mention your dd in your posts but she must be suffering so much. Her dad is in and out of her life, there are screaming rows often, her mum doesn't sleep at night which exacerbates depression and therefore is often tired and unavailable.
You love your dd and you seem like a nice person who wants to have a better life, please stop focussing on this relationship - it's fucked, it's unfixable, it's destructive, it's dead.
