Need opinions: Saw friends with benefits on a date with a girl. He smiled and then panicked? We’ve know each other for almost a year now?

Met this guy and we both noted an immediate attraction/familiarity. Now I’m the type most guys try to wife up. He’s a guy girls see as the meal ticket and would play the long game in hopes of having him. I don’t play that game, bc I don’t need a meal ticket. to which he noted that I was a unicorn. Yet There was something off about him. so when he proposed a friends with benefits situation I was completely game. We would have long conversation for hours at his place drinking wine and then sex. After sex, we shower together and we go on our separate ways. Despite Wayne being a “catch”, building wealth, and exhibiting great potential as husband/father, he has no clue what he truly wants in love/dating. Having learned his dating past where despite his prideful claims of knowing what he wants from a partner (wholesome qualities), he would pursue the exact opposite. Mind you, when we talk, there are always moments where he would look at me and say things like “I mean who’s to say we won’t eventually end up together. You exhibit everything I’m looking for and vice versa” “you’re beautiful, wholesome, and intelligent” “wife material” and throw breadcrumbs like that. And though he insisted that we could end up together, I made it clear we are just friends who happens to have sex. And that would bother him. Last week, I came across him in public. I walked towards him, smiled, and waved. He happily smiled, but then immediately tensed up and got nervous. In that split second I realized he’s on a date, noticing the girl by the tables. Before I could fully stop and say “what’s up!” He’s like “I’ll message/talk to you later”. So I kept walking and continued my phone call with my friend and laughed. Doubt that girl is a “gf” yet since she’s different from the girl on another date (first bump in) where he didn’t even acknowledge me lol. for someone who is so confident in life he cowered real fast like he was nervous. I don’t get it. Why make it awkward? We’re friends for 1yr now. 

Also extra info: I even told him in the past I can be his wingman. 😂 I doubt how I would react is what he was panicking about. But then again… *shrug
