Hurt by my partner

First, I want to say that I am so sorry you are going through this! Being a mom takes so much mentally, physically, and emotionally, and you deserve support through all of it.

You do not deserve this, and you don't have to blame yourself for the situation you're in. So many women go through this, and you're not wrong for expecting someone who wanted you to keep the baby to step up and be a teammate with you! You can love your baby more than anything in the world and still feel overwhelmed, exhausted, and angry that you're doing it alone. Those feelings don't make you a bad mom!

I'm sorry you're having to deal with all of this, especially while you're sick. Please prioritize your health and remember that you deserve to be cared for, too. ❤️ You're absolutely not crazy, and you're not alone in feeling this way. Be kind to yourself! ♡♡♡

You posted 6 months ago that you wanted to leave him. It sounds like he is beginning to show some emotional abuse and some coercive control - guilt tripping you for wanting to meet with friends is a red flag.
Reading what you’ve wrote you are incredibly vulnerable, healing from birth and now freshly postpartum.
You are also dealing with a teen father who doesn’t seem to understand the weight of responsibility he now shares with you.
Does his parents acknowledge he is doing very little? Do they pick him up on it?
Where is your family?

It’s not your fault - you are not responsible for how another person behaves or chooses to act.
What you need to decide is how long you will be able to tolerate the behaviour, lack of support and the impact it’s having on you emotionally?

Whatever you do. Be selfish and put your and your child first.
Do not let anyone make you feel uncomfortable or guilty. Because your mood, your temperament and your personality wellbeing directly impact baby
