Should I tell a girl that her boyfriend sexted me early in their relationship?

I month before I graduated from college, I hooked up with a guy who came across as a little douchey, but I really just wanted to have sex before I graduated. I was convinced that I would never see the guy again and I never had any plans to speak to him again.
Three months ago, he wound up messaging me through Instagram and made a bunch of sexual comments through my DM, saying how he was in my city, he wanted to "hang out", where he should go to meet "hot" women in the area, and how he'd "pay to have sex with me" if I offered it. He then said how "tight" my vagina had been when we had sex, and how it wasn't built like a "loose can of soup". I was grossed out and told him to stop bothering me. I then went onto Facebook to unfriend him, and it turns out he had a sweet-looking girlfriend who'd tag him in posts saying things like, "I have an amazing boyfriend! Love you, babe!"
Now, it looks like they're engaged. I never contacted her initially, but is it worth it to say, hey, your fiance was sending me degrading messages, he might be an asshole, and he sent me these messages when we were dating, FYI?

P. S. I'm 22. My age on here is wrong.
