No one deserves to be cheated on. The way he cheats on her is horrible and unacceptable. I empathize with her, but she needs to let him be a dad, if he chooses and move on with her life. She's a beautiful woman and seems to be very compassionate. She's wanted a child for many years so she has her blessing and count it all a joy that she found out about him now and not later. She can do better and sometimes it's okay to just love yourself and keep it moving.
