My husband used to push me around and threaten me that he'd leave me penniless and take our kids away permanently...He never took me on a date, ever...He liked to read his own things and was grumpy all of the time, especially if "we" bugged him from his own aspirations...
That being said, yes I met someone online and it evolved like crazy...I was scared of my husband and his threats, I never felt loved, and I wanted to have a home with my kids...Yet there was the "me" part that was left over, that's where someone got an "in" with me...
My husband died in a car accident, and then the online affair fell apart, and I felt guilty though I never met him and though my husband was purely a *hit towards me...After he died I learned my dear departed was already making lawyer plans to destroy what little I had (my kids, I have no family)
sometimes the online thing is only a fantastical exploration of "what ifs"...To me I was too scared to leave, he'd have tried to ruin me and take my most precious things...My children...I never even knew if I was attractive, I never knew who I was, all I knew was the denegration I got from my husband...
I know she's cheating but if you care to know why you might find that she does need to know something about herself that she's not knowing through you...For me it was that I could be loved, that I was lovable, attractive...These are basic human concepts, and if they're not being fulfilled in the relationship, people will go outside of the relationship...
I'm a widow now and got life insurance and my kids, and I had a hard time grieving over their daddy, really I did...I still shudder at his physical attacks and verbal threats and telling me I was not as good as "other women"...His family heard only about the online affair, and they dis'ed me totally and don't even talk to our kids (now none of us have any family at all anywhere) and never knew of his abuse...But it's ok to get as many dysfunctional people out of my life!
I'm in a 5 year relationship now, this man just loves me, my kids, and worships the ground I walk on...I have higher self respect than I ever did, and because I was an abused/neglected child I did not have expectation for good treatment entering into marriage, but now I do expect to be treated well (even if you don't expect it, when you don't get treated well it still hurts)...
