I have been dating a man for almost six months. This has told me or speaks to me like we have a relationship.?

He as always showed me respect and has been quite the gentleman. Now suddenly an old girlfriend has come out of the woodwork, he was told me that she suprised him and told him that she was flying out yesterday and that she would be staying with him for about a week. I feel that he totally disrespecting me and my feeling? What do you think
