I blame myself a lot with good reason for making her feel the way she does now,
This has nothing to do with her betrayal.
She is simply using the lull in affection/attention as an excuse to act on her insecurities and lack of self validation.
I’m sure at some point she was not 100% affectionate with you.
That would NOT give you any excuse to betray her.
Relationships go through ups and downs and the downs are not an excuse to stab someone in the back.
She basically said that she loves me as a person and always will but doesn’t know how to accept my apologies in fear of being hurt again.
What a pile of steaming horseshit this is - I think I’m going to heave.
This is pretty much a confirmation that you are being used for your financial support for her and her children.
This is the essence of being strung along.
From Butforthegrace:
You ignore her for months as she pleads for intimacy. She turns to another man. What a surprise.
I hope his intent here is not to imply that you caused her to “turn to another man” because that is absolutely false.
Her betrayal is not because of anything you did or did not do nor because of anything you said or did not say.
My ex-wife was denying me attention, affection, and sex while providing all that to some guy as well as being incredibly financially destructive to our family.
I didn’t “turn to another woman” because of all that - I divorced her ass.
Look, stop with this self-blaming bullshit.
Your girlfriend’s reasons for doing this exist only within her and existed within her long before you ever knew her.
She just thinks she has an excuse and someone to blame in order to act on it.
This one is cut and dry.
You are not married, no children together, no major assets apparently, and you are still young.
She is emotionally abusing you as well as financially taking advantage of you.
Put and end to this unnecessary suffering and end this farce.
You do not deserve to be treated like this and you need to work on yourself to find out why you would be so tolerant of it.
You have received some very good advice so far.
Let your anger come out and be assertive in your desire to get yourself out of her world of infidelity and her abuse.
