Tip. Give each other lots of space in the marriage. True for all relationships, anyway! I'm in this kind of 'mixed' marriage and just had our 4 year anniversary last week. Giving each other space made all the difference for me.
Communication can be challenging if hearing spouse isn't good with SL, and you are a native SL user. You have to have a lot of patience, and things will be ok.
My friends and family are ok with my hearing hb - he is a kind man. His family had a problem with him being married to a deaf woman in the beginning, though - because they didnt understand how they could communicate with me if I couldn't use voice. I'm sure they were worried I'd be very dependent on him for everything. I was "intimidating" to them.
Things are ok - I proved myself to them, and they all have accepted me. Their relationship with my hb became better, because I encouraged him to be nicer to them. He was kind of mean to them before.
