I am sorry to hear you are struggling. It’s possible you were lonely and vulnerable and fell prey to toxic man. No it will not get better. If it didn’t in 5 years, it won’t.

There are wonderful things you can do as a single person. Hobbies, volunteering, going places, enjoying your house to yourself, doing things your way and maybe trying to make new friends? I’d say everything sounds better than being in a toxic relationship. Do you live together? Depend on him financially? (Hope not)
