I say feel out the situation.
If he seems like a twat to you he most likely is.
so go in holding no bias and let him dig his own grave
If he starts acting severely over attentive test him on it. Ask him what he likes about you etc etc. If he's ready to start another relationship.
Being a guy if I am looking for a piece those questions will scare me off of that lady if I dont want a relationship.
My best advice is use your gut instinct when you meet him and always remember NO MEANS NO
