Sorry for your loss...you probably should tell him soon...The loss I felt was more then I expected when I had experienced it.

I think much has been said in this post is good...

Only thing to add is that if this is salvageable at all...you probably need to sit down and have a candid conversation with him...

Us guys when hooked on climbing the ladder - may do so at families expense...realizing to late. Sometimes you have to work less for the greater good...

Might I suggest also that you not have intercourse with him for a good amount of time...you will see what he is up to fulfilling your needs...and at the same time not risking making more babies with a guy who will not be a MAN when the time comes.
