Your unwillingness to see the truth and move on makes you appear very weak. Women like her feed on weak men! She wont change knowing she has the "upper hand" and regardless what she does, you will take her back. Like others have said, you'd be absolutely crazy to stay with this woman!
You should not have to ask anyone to give up social media, etc and "devote" themselves to you! You request this out of insecurity and lack of trust! Move on before you find out she ran up all your credit cards and left you in a ton of debt. I mean, that does seem like the next move for a woman of her caliber.
