How do I get this friend to actually listen to me?

I, 26/F, have this friend, 27/M who I'll call Jake. Jake and I have been friends since we were kids. He's into me and I WAS into him when we were younger, but it just never worked out where we could give anything a shot. He's now in a relationship with two kids of his own and I've respected that because I don't want to be a homewrecker and have tried to move on. Here's where I need the advice. Jake has come onto me more than once since he's been in his relationship asking for intimate things or to see me "get off" which I've always rejected. There was one time years ago when I got tired of hearing him ask for stuff and as an attempt to get him to stop I took off my top for him, which I regret now and I know I was wrong for that incident but I just wanted him to stop asking for stuff. That obviously didn't work and no matter how I try to explain to him that I don't want to do anything like that with someone in a relationship he keeps pushing still. Anytime he "jokes" around and comes close to my face with his gentiles, still in his pants, or acts like he's going to take them out I freak out and say no or ask him to stop. Anytime he brings up doing anything sexual with me I tell him no or just stop talking because I don't know how else to explain to him that I don't want to do anything with him. And he makes these excuses like his girlfriend is okay with him doing things with other women, the fact we've known each other for so long should mean I'm comfortable with it, or, more recently, he's asking because he thinks it'll help me with my "funk" and maybe I'll actually get up and do something (I struggle really bad with depression and it's affecting my availability to keep my house clean). We got into a fight the other night when he brought up that last excuse and he made a comment about him being tired of my "mixed emotions" because he thinks I'll be fine with him doing something like pushing his genitals in my face and then I'll freak out. But I don't even know what I'm doing to make him think that is okay. I literally just lay or sit wherever we're at and try talking to him like friends should be able to do. I don't joke about having sex with him, or anyone for that matter, and I don't go out of my way to be revealing. I just want him to stop acting like he's entitled to get anything out of me just because we've known each other for as long as we have. I just want him to listen to me and I don't know how else to explain it to him. Maybe I'm doing something subconsciously that I don't realize I'm doing? I just want him to stop.
