Should I stop talking to him

So there’s this I guy I really really like his name is Tyler we’ve been talking for like 2 months and we’ve had sex twice. He claims he likes me too but I just seen that he told this girl that he wants to hit it from the back should I be worried and just stop talking to him and let him go or am I jumping to fast because I know we never established that we are in a relationship. Should I approach him about it ? I’m heartbroken about
