Should I keep seeing him?

Hello ladies I need some advice I’ve been talking to this guy I met on tinder for a few months now but when we first started talking he kept something big from me it wasn’t till a few months later that he told me he was married but he really liked talking to me and he didn’t want it to affect us but I obviously knew it wasn’t right to keep in contact with him so I cut him off but he would Snapchat me often...it wasn’t till my birthday that he told me he was getting a divorce, he moved out and was living on base (he’s in the army) he was always asking me to meet him in person until one day I invited him out to a bar and we hit it off I loved talking to him that same night we had sex and even since then we’ve been hooking up and he recently told me he was seeing his wife but just for sex should I keep seeing him or should I stop I’m so confused he says he loves having me around but I don’t want to get in the way of things if he’s not going to get a divorce.
