Once trust like that is destroyed especially even before the wedding......there is no way to really ever restore the feelings of trust or even a safe marriage feeling...it that you will never know when he will decide to just blow off the marriage I go for a divorce......so it's better for you to take the action first.

If you are in the last term of your pregnancy, there isn't much that will really effect the baby in a negative way by this point.....shoot, I was doing down hill skiing the week before I had my baby & my last month was so stressful I lost 10 lbs because I was stressing about the fact that I was going to have to have a c-section because my baby was too large to deliver naturally. You might be stressed but your baby is fully developed at this point.......there will basically be no effect......so what you need to focus on in you & your babies well being.....& getting support from this guy is probably the best thing at this point in the whole mess....but you really need to go to a lawyer & get input as to what the best way to proceed is.
