Without chinese input support, I firstly answer some technical
questions.

1.Although his sun and saturn are in your 7th house,
this doesn't mean your stellars are in his 7th house.

2.Lack of his birth time, I cannot offer too much informations for you
about his attitude towards you, because some important message
such as Ascedant,MC and other houses are not available.
So if possible please tell me his birth time and I will give
you some advanced advices with my best effort.

Any way, I will answer you these days.
