My girlfriend went through my phone, what should I do?

Eng_Lad
An old friend was texting me, then she went out to a party, got drunk and texted me saying she wanted to "f*** me in every position." I was at home with my girlfriend and text back, "whoa, steady on, your obviously enjoying your party so go have fun". I went downstairs for a drink and stuff, came back up an she said she'd set me an alarm to get up an let me know the other day that she'd looked at all my messages and began asking who she was! I was so angry, an she must not trust me at all so what do I do?
