No mentalradio, I can't help you understand it, but I've experienced a similar incident. At Christmas my H insisted on getting D11 a cell phone with capabilities that I didn't think she needed or was ready for. Anyway, he told her that if she didn't use it responsibly he would take it away from her. A couple months later I get an email from him telling me to tell her that she needs to stop downloading things on the phone as it was costing him extra money per month. I told him that was his deal and he should talk to her about his concerns. Come to find out what D11 was doing was receiving ringtones from her cousin and it was costing extra which she was unaware of.
Anyway, he told her that he had a problem with her not being responsible with the phone after he warned her about it when he gave it to her.
D11 understood where he was coming from, but wanted to know why being responsible was so important to him when he was the one that turned his back on all that he was responsible for and walked away.
