ive never been cheated on or cheated myself.
my dad, however, had cheated on my mum. even ran off overseas (back to russia) to be with the other chick and even stole mine and my sisters' birth certificates to divorce my mum without her presence.. anyways i don't know whether or not my mum has genuinely forgiven him, but to this day they still sleep in the same bed and i think still have sex... mum claims she got back with him for my sisters and i, especially for my little one, who is 12 years younger than me, so she can grow up in a 'normal' family with two parents. our family is far from normal lol.
anyway, this experience will definitely make cheating unforgivable for me. i wouldn't put up with the person who would do that to me, no matter if we already have children or not.
on this note, my boyfriend's grandfather and father BOTH had separated with their wives, found someone else 10-20 years younger than themselves and had a kid (boyfriend's dad's new little girl is like 6 months old now).. and this makes me suspicious of it running in the family and my boyfriend also falling into the crazy middle aged man ordeal.. our relationship is pretty serious and we always talk about living together and having a family. and when i think about him cheating, i fear that i wont be able to let go of him and make the same mistake my mum did
anyways time will tell lets all hope for the best lol
