Should I mention to my boyfriend about this guy, something with him is off?

Before my current boyfriend, I used to have multiple sex partners by choice or one-night stands but once we started dating I said goodbye to all. A lot of my friends don't support it cause they thought I'd have a fling but one year later, we are still together. Sometimes I miss my previous life and the fun but I wouldn't trade it for my previous times. The thing is that I have my friends on the one hand who say that I'll get married and they'll lose me and on the other, some guys I used to meet that don't get that I am not into that anymore. There is an ex-colleague of mine that we used to meet casually but I cut him off once I got into a relationship. Lately he started commenting under my posts, liking all of my pictures, texting me in private giving me compliments and shit which make me feel uncomfortable since I told him multiple times that I am not interested and he knows that I have a boyfriend. He started bugging me more and more and few texts became daily ones, and I started feeling suffocated. He claims that we are just friends. Now he wants to meet with me and my friends or party together but I don't trust him he's kind of sketchy and he used to be known in the work place as having a d* attitude. Clearly, he's not in my circle of friends and I don't intend to include him but he started becoming obsessive and I don't like it. I haven't mentioned anything to my boyfriend cause he has a tantrum sometimes and gets jealous. I am kind of bugged atm by this guy and I try to keep it polite cause I don't want to block him. If I don't reply to his texts, he'll send me some more. Is this normal, wanting to chat all the time? I don't chat with my friends that much and not even with my partner. Or should I try to cut him off politely?
