Is he normal or just tricky?

i met a guy,he is really a big guy both in age and financially.we've dated for 6months now but he really turns me off.he never talk unless u ask a qtn and give brief and precise answers.he lives a lone in a big house,never talk about his past or family,wonder if he is hiding s'mething from me.never talk abt our relation ship,how he likes it or any thing.never calls to say hi unless he want to see me.do u think he is normal or he is psychologically totured? he is scaring,doest enjoy jokes and rarely smiles though not tough.iam always afraid of what to say when we meet. sh'ld i go on with him or its drama?
