Male snake 1965 & Female Ox 1961

Hi.he was born 2/19/65 I on 11/4/61. He is the one who pursues me then turns cold then pursues. We are from different countries but when we talk, so much of same belief systems. He is different mannerisms vs US me, but tells me he enjoys me very much. Problem is, he has my interest which is hard to do then pulls back. He tells me in mo telationship but my intuition tells me he's hiding something thus goes cold?
