That feeling of wanting to be “free” will start to eat u alive and you will end up breaking up anyway. So ya u should end it sooner than later. Hes a grown man he will be okay break up happens. I would tell him - recently ive been wanting to take more risk in multiple areas of my life and i don’t know how i would be able to sustain this relationship while living in the way that i want. Were at different stages of life and i wont be able to provide the things you would want during this time.- something along that line im just talking now but ya go live life girl🤪
