Boyfriend is convinced I have been cheating. 36F 36m

My 36F boyfriend 35m has been convinced that I am cheating. He claims he has paid somebody to hack my computer and passwords. And claims he has found my “partners” and dating sites. He claims this is because of old emails I have that I use as back ups to my main account. But is really claiming that the person he paid “exposed me”

Big problem here is I have not done any of those things. I’ve never cheated, I don’t have dating profiles, hell I barely get to talk to my friends or family because he freaks out.

He accused me of being gay because when a female coworker of mine came around he was drunk and high and embarrassing therefore I wasn’t touch with him. He claims this means I have a secret crush on her and wants to act cool. I tried to explain his behavior was cringy and embarrassing but nope it’s I have a secret crush.

I have told him I’m going to move out and won’t tolerate the accusations. Also I gave him until Jan 1 to get a job because in 2.5 years he’s been unemployed for all but maybe 7 months of it total. And was fired from his last job for an argument with his supervisor.

I have devolved into name calling such as “little bitch” or other “emasculating” terms as he says because the insane accusations are making me nuts and I can’t help to lash back when someone is constantly accusing me of shitty things.

Recently he found out we got a credit on our power bill but I never deducted that from the amount we put in the joint account. Seeing as we both put the equal $1200 and spend it only on household joint purchases. He claims I’ve made him pay bills that don’t exist. But it’s just the extra being used for Costco runs Walmart etc. and once again I’m paying equal amount into the joint.

We’ve been dating 2.5 years.

I guess my question is when do I call a family member of his because it’s like scary delusional and I’m worried for him?

EDIT: clarification- Should I call his family so they can help him
