Need some advice

Okay so In July of 2017 I quit work at a body shop because my husband didn’t like me working there around a bunch of guys, which honestly was for the best so no comments on how my husband is controlling, we just needed a job and it was offered to me at the time but I didn’t want to be there anyway. Long story short my boss started harassing me, sending me text messages of sweet nothings, writing on my road telling me he missed me (yes my freaking road that I live on, in paint) he FOUND my place of work about an hour away from where HE actually lives and put flowers and a card on the windshield of my car. He got wind that I was pregnant and sent me texts saying “I bet I look beautiful and have that beautiful pregnancy glow” whatever. Literally I would get 10 AT LEAST text messages a day. I blocked his number and just yesterday got a message from his wife “I know you’re still talking to my husband he admitted it to me and if you

Don’t stop I’m going to start talking to yours about all the stuff my husband told me you

Said about yours” I didn’t respond as my daughter is in the NICU and i really don’t have time for this immature bull shit when he’s been blocked for 9 months now basically. I’m sure there’s more that I could say that this asshole was doing to Harass me but i really would like to know what to do as my husband and I don’t need it like I said. Obviously this dude is already lying to his wife about the situation to make matters worse so what other lengths will he go? I could get a restraining order but I’d rather go the route of something else first if possible. But it’s frustrating because I have all sorts of proof and evidence that I told him to leave me alone back in July and she will never listen more than likely.
