I don't understand why to destroy your mobiles, accounts and computers?
If your GF is soo much dear to you, that you are willing to destroy all your stuff for her sake, why would you have or do something that she wouldn't like?
If you are still having/doing something that you know she wouldn't like, it means that she is not so much dear to you, then why not to let her go to hell along with her demands, rather than destroying things?
