wow...you are one strong woman....forgiving takes strength...
I have a friend....she has been my strong supporter in my reconciling with my H....her husband left her with a toddler....he got involved with an OW...OW got pregnant...he returns to his wife when his child with OW is about 2 yrs. old....child was named after him....gets joint custody.....wife gets pregnant with twin boys...she is a good step-mom....treats OW's son as one of her own and loves him like one of her own when he is with them...
They have now been back together for over 10 yrs.....H is totally in love with her....he did have a second OW during the time he was gone but she has forgiven him all his past misdeeds and they have such a nice family...very loving relationship...
So there is hope even if the OW has a child by H....it is hard but not impossible...
