To me being faithful in a marriage is of utmost importance. In our marriage vows we promise to be faithful and only be with each other and no other. Once someone has cheated on the other, the trust is gone. Some are able to overcome in time, but for others it never returns. The marriage is damaged forever.

I am not sure what you are trying to say. Do you mean: What do you think about faithful human beings? [ being a faithful/ true friend] OR What are you thinking about, faithful human beings?[ what is on your mind?]

ı think they are best humans for me...
