Should I still fw him?

So I work with a guy and we all know he has a girlfriend or wife or whatever and I tend to not break thinks up. I’m not a home wrecker but he came off to me and we smoked and chilled one night and then he left. Time passed and his wife texted me asking if it was me and I’m gon step so I said yes. After that she never responded... recently I found his FB and added him. We exchanged numbers again but he hasn’t hit me back or up. I understand he has a baby now but I’m kind of confused because I thought that he was co-parenting ... at this point I jus wanna see what it’s like and that’s it .. if his wife is txting my phone it must be some kind of good but i don’t wanna be pushy ..
