Advice!!!

Long story semi short. Okay about a month and a half ago I dated this guy for about 3 weeks. Only seen each other on the weekends. Okay well I broke up with him for certain reasons that are irrelevant. Okay so I started seeing this other guy who happened to work with Adam. We're keeping it quiet because we don't want Adam to know. BECAUSE Adam has been confiding into him about how he knows he fucked up and keeps asking mike for advice to get me back. Meanwhile he doesn't know me and Mike are seeing each other. And have been seeing each other for like 4 weeks. Every time Adam Goes into work he nonstop talks about me. Well the other day he showed Mike a bra pic I sent him. Obviously he was upset by it, but that was before us so he couldn't get mad at me. But he told me Adam was going to come to my house and wait for me to get home so he can force me to talk to him because I haven't been texting him back. That's because I haven't got anything from him cause I changed my number. He doesn't know that tho. He's starting to make Mike feel bad tho. Because he feels like he's in the way of us getting back together. But I don't wanna get back together because he is addicted to porn and beating off and couldn't get hard for me or have sex with me. Anyways. Idk what to do about Adam. I want my name to stop coming out of his mouth. He needs to forget about me. I feel like he's obsessed?  Everyone else at their work knows me and mike are together. Except him. Idk what to do.
