i need your opinion. help?

Hello! So I’m currently in a situation where I am torn between doing what would make me happy and doing what’s practical. Here goes:
I’m currently working in a BPO industry for a year and 3 months. I was recently promoted from an agent to a trainer. But there’s no increase in pay. Anyway, being in the training dept was toxic for me. Not because of the workload but probably because of the people. So I handed in my 30 day notice of resignation. My fellow trainer also handed in his notice because of issues with his yearly appraisal. My boss came to me and asked me to extend my stay in the company until the end of June because if I don’t stay with them, he said he’ll die. Very dramatic I know.
So the issue is this. I want to resign so that I can go home and help my man with the family business. That would make me very happy. But I don’t want to disappoint my bosses either by letting them down. My man always tells me that I’m too nice for my own good and I don’t need to feel bad by doing what I want. But I have this sick feeling everytime I disappoint someone or if i feel like I did even if we’re not related or in any close relationship.
Your thoughts please? Be completely honest. And I thank you for taking time to share your opinions with me. ❤️
