re: my ex left me again and its tearing me apart (Please give me some advice/insight)

Up until her insecurities make her question me who I was texting and was I talking about her to whomever I was texting. I was talking to a guy friend who was in town for Mardi gras and I had no problem showing her my phone. She took that time to go through everything. Emails, contacts, calendars, Facebook I mean everything. I didn't mind because I knew I wasn't hiding Anything. So we go to dollar general to get some items and yet again she is asking where is my phone. I said its in the car and I don't care about it. So while we are at the register she starts texting and I walk near her and she turns away so I couldn't see anything she was texting. So I grab the bags and go to the car. While driving I ask her, since I gave you my phone when u wanted it may I see yours to see who u are texting. She said, "No!" I asked again and said please. Again, no. She knew I was hurting because she wAs being hypocritical. I told her to get out of my car (we were back at the hotel). She got out but I watched her and her phone. She wanted to Erase whatever but I watched her closely. So we get back into the room and I grab her phone she holds it tight as hell. Then I grab her other arm and I pled with her graciously and said, please don't hurt me I love you. Just show me your phone. She gave it to me but it was locked. I asked for the password she didn't give it to me. She starts packing her stuff and she said in afraid of you. She grabs her stuff and asks to talk outside. I obliged she then storms off and didn't talk to me. She goes into the lobby of the hotel and begins to watch Netflix. I was like, wtf! Talk to me. Let's fix this! She says no lets not do this in the lobby. So I leave and come back and she is now sending emails to my previous ex that she alleged had called her. I'm like, why are you doing this. What does that have to do with anything. I'm not with her nor does she want to be involved in our drama. She then goes to the agent at the desk and says could u call the police im afraid of him im dead serious. Again I'm in awe!
