Recently my teen dd (almost 17) and her long term boyfriend had a short break up. From snooping her phone, we've found out she has had sex with another guy aside, which she told the boyfriend about. She was really upset with the breakup and pushed very hard with loads of promises to win him back. They got back together.
From phone messages we've found out she is still messing around with the other guy and has sneaked into his house and he into ours through her window.
The catch on all this is that we've found out the info from her phone without her knowledge and don't really know how we can confront her. We think we need to 'catch' her out first but that may take a while. We're really upset and angry, especially for her lovely boyfriend.
