He was away for work, so it was not because we were fighting or anything.  I have been questioning our relationship and that is one of the reasons why I broke down and was unfaithful.  We were trying to have a child he really REALLY wants a child.

I understand what I did was wrong and when he came back I know that I want to be with him...I am now leaning either towards telling him the truth and be prepared to be a single mother or terminate the pregnancy (which I am not very fond of) and never tell him about it...
