So over the course of the last 11 months I have witnessed strange behaviour from my GF. She received a slew of text messages while sitting on the couch. She looked at all of them except from some guy. I kinda wondered about this but said nothing. She then left to bring the garbage out with her phone and when she got back and put the phone down I noticed that the text had been deleted. Couple months later we are at a party and its like 3 in the morning and keeps getting a bunch of text messages. She leaves the room and I grab the phone and she gets a message from some guy asking if I am around? I notice that all messages prior to this are deleted. I say nothing but feel like that is so strange and makes me feel like thats such a strange thing to ask her. Then a little while later in the month she gets more messages from someone who she claims is just a friend. She wont let me look at them when I am around. I ask her to see the message and she refuses saying I dont trust her and gets super angry and defensive. I said if she had nothing to hide why wont she let me see. I have never minded my girl from having guy friends and shes hot so its expected that she will get hit on.
