Salamu Alaykum Sheikh, My family is not muslim and want to gather together with my wife included because i just got married, but there also non-mahram men. How can i deal with this situation without breaking ties with my family?

This is not called breaking ties, breaking ties is when you cut them off and ignore them for long. As for freemixing this is not allowed.
