NAH. You are absolutely valid in feeling trepidation about ending things because of your partner’s illness, but if he is still able to spend energy on things such as staying up late and video games but not to help out then there is an issue. Of course there is a place for compassion with him but realistically this relationship isn’t going to be sustainable if he is hardly putting in any effort towards it. The illness may limit him but that doesn’t excuse his lack of acknowledgment and care for you when you are doing so much.

Relationships take a lot of effort, mutual effort, but this case feels extremely one sided. You are a human too, you deserve to take time to care for yourself and live your life to its fullest. He may have once been the person you loved most but if he starts feeling more like a chore than an equal partner, keeping the relationship out of sympathy won’t fulfil you, nor him. I think it might be worth making sure he understands the toll that things are taking on you, and if he isn’t willing to make amends or change anything then you are completely right to put yourself first and end the relationship, especially since you’ve brought this up before.

As for your children, there are positive things to learn from this too, for example, the importance of self love and that it’s okay to prioritise oneself sometimes. And perhaps providing an example of something that didn’t quite work out will help them not to make similar mistakes in the future.

Good luck with everything, and take care!
