Dating a man about...............?

4 months and our time spent together is him coming over to my house and having dinner or watching movies.drinking etc.. so today he came over to put a new battery in my car and he was so awkward outside...he did not even hug me or kiss me when he saw me but I went to kiss and hug him when he left although there was NO pion like we share in my house..but inside my house he cant keep his hands off me :( I asked him if he was nervous about PDA's he said he was sorry and he would make it up to me ..im sooo upset since this happened today! I love holding hands hugging kissing and a man wanting to be close to me not just behind closed doors..we are both 40.. what do you think ? thanks so much..
