Do I tell my husband?

Some of you saw my post about a month ago about a co-worked telling me to kill myself. I didn’t proceed with it, I didn’t go to HR, as I know if I try to cross him there’s going to be hell to pay. Anyways since then he kept sending stupid things, today he sent another post (smth about the virus) in a group text, I responded with a “thumb up” emoji, to which he responded with the bunch of “middle finger”. Anyways I sent him a private message saying don’t include me in any group texts or send me suicidal videos anymore. He replied in all caps with f*** you. I tried and still try to be civil, I hate being in war with someone, I don’t like being threatened in any way, he is the type of person that if you cross him he won’t stop until he ruins my life. My question is, now that I’m in quarantine it’s totally fine, but I cant help but think about all the harassment that will come once I go back to work. And the most ridiculous thing is other co-workers will probably side with him, or think that I’m too sensitive and overreacting because he is just a troll. Well I can’t help but get this way! Should I tell my husband? He knows him and hates his guts, if I tell him he will go absolutely crazy. We already have so much going on I don’t want to burden him with this stuff.

Thanks everyone
