I have been seeing my girlfirend for a little over a year now, at the beginning of our relationship, i noticed that she had a few male friends from her past that she still kept in touch with, and i told her i would be more comfortable if she didnt talk to those guys, she stopped the snapstreaks with them and i thought everything was fine. A few days ago was her birthday, and i am on vacation at the moment (we live two hours from each other and only spend time together on weekends) so i came to stay with her for awhile in her apartment. She went to sleep pretty early, and i was up really late, i heard one of her friends text her, im in the dining room on my laptop and her phone is right next to me while she was sleeing in the bedroom, i couldnt resist looking through the phone, and i went right to her Snapchat. The same guy from the beginning that i asked her to stop talking to, wished her happy birthday, and i slide up to see the conversation and there are two pictures of my girlfriend half naked in the chat saved. I woke her up and we talked about it, she says she doesn’t remember sending them, but i just don’t believe her. For over a year this guy has had access to these photos and all she had to do was delete them from the chat, its like she wanted him to see. I feel betrayed, i cant realy look at her the same way knowing that this dude has been kwwping in touch with her our relationship, i dont really know what to do, any advice? Ive been really really sad since this happened
