I really don't know what to do.
I noticed my girlfriend gets these FB messenger texts come up now and again on her phone and she will never open them in front of me. From a few different boys etc but thats fine, I trusted her etc. However one was from an ex that now lives in scotland and they were really good friends before dating dated then he moved away. i asked her about this and she said it was nothing etc but lately she has been acting differently and being a bit secretive so her fb was open on my laptop whilst she had a shower and i though F*ck it ill have a little look just to settle my thoughts so I dont need to worry about it.
Turns out there are loads of messages to and fro from this ex, some of them quite explicit about when they were together in the past, mainly from him but she has made no effort to make him stop these messages, one was a very detailed message he sent her about a dream he had had about doing stuff to her etc.
I then kinda brought it up when she came back by saying I've noticed messages come up on your phone etc which is worrying as theyre from your ex etc and you never open in front of me she said they're just friends etc etc so i leave to go home as she had work soon so I go home and go back on her account to screenshot these messages if need be for evidence and now they are all gone.
She must of realised i was on to her and now she has deleted all the messages between them.
Please, my head is all over the place, what do I do !!!
I love her..
