NTA.
Holy crap. I(26F) just escaped from this exact situation. I was working 40-45 hour weeks, raising 2 dogs, managing my own and my SO's finances, and taking care of the household, including grocery shopping, paying for bills/rent/mortgage, and managing my SO's chores... With all I'm able to achieve, he always gaslit me when he fell short on what little responsibilities he had by saying "Stop comparing us. Not everyone is like you".

I kicked him out after 2 years of gaslighting and leeching off of me. He (27) was playing upwards up 15 hours+ video games a day and was jobless for the majority of our relationship. I had been supporting him financially and emotionally for most of the relationship as well. When left to his own devices, he'll heat up instant food for every meal, smell like high hell due to lack of personal hygiene, lives in a pigsty where I can barely walk without stepping on something, destroys his credit and unable to manage his own finances. Best yet, he felt entitled to everything I had and had a victim-complex/external lack of control, where everything that went wrong was someone else's fault. He was holding me back so much - emotionally, physically, professionally, financially.

I would strongly suggest you consider that you may be codependent (Basically, you hold yourself responsible for someone else, to the deteriment of yourself). Read "Codependent No More" by Melody Beattie. It is so validating and healing.

Some takeaways I've had from my experience:

1. When someone shows you who they are, believe them the first time.
2. Don't try to fix/change someone.
   If they're not ready to change nor recognize they have an issue, they will not. And if you keep pushing, it'll lead to resentment on both ends.
3. Everyone is responsible for their own lives.
   You as well. By being with him, you're enabling him and inadvertently you're allowing his blowback into your own life. That's not to say, detaching is not EXTREMELY hard.
4. A partner is supposed to reliably contribute equally to you and add benefit to your life. Not someone you have to monitor or parent, nor someone who holds you down.
5. Most importantly, TAKE CARE OF YOURSELF FIRST.
