Is it normal that i cant trust my girlfriend after this?
Good evening.
I was in a relationship with a girl for 4 years. Before me she was in a relationship with another guy for 9 years.
Long story shortened after a few months of dating I found out that a couple of her guy "friends" (3) were not her friends. They were her allegedly "ex lovers". It turns out she cheated her ex for 4 years with more than 5 different people and thats what I know of (she confessed after I confronted her about this). She was hiding and deleting messages with them and even went so far as to have a fake facebook profile to chat with one of them.
Needless to say my heart and image of her were broken, trust was obliterated. With mutual hard work and time we managed to get over that and rebuild trust. I was never following her, checking her phone for messages, none of that. If I found anything suspicious I asked her about it and what she told me I believed.
When we were going through that I told her that we can stay together but if she ever puts me in a situation where there is a second, unknown guy in our relationship and there are suspicious things about that guy, eg. That she is deleting texts, hiding stuff... In that case if I need to wonder if she cheated on me with him or whatever is going on, its instantly over. I went through that once, dont want it twice.
4 years later, I accidentally find out she is texting her boss with the keep quiet emojis as she saw me approach her I told her to scroll up, a few messages before that she texted him "Air is clear, you can type now".
I didnt look at any other messages or anything else, just broke up with her then and there. Helped her pack up and drove her home, helped her get her things up the stairs. We went apart in "ok" terms. She later admitted that she deleted messages after every chat she had with him and that he was sometimes innapropriate.
Her reason for these secret chats with him was that we were going through a tough period because we couldnt agree on when to have kids and I was depressed due to many family members dying close together so she seeked help in talking to him about us and about me and she thinks I would have gotten angry if she was talking to him about private things so she kept hiding it. She knew about our deal and admitted she figured she wouldnt get caught.
In all honesty due to her history with her ex and with me and our deal, due to everything we went through to repair trust, due to how much she kept staying after work with her work crew (and possibly alone with him but ill never know).... due to all that I simply do not buy her excuse, I do not trust her any more even tho I wish I could, she has no proof or evidence of her not cheating or what those chats were about since all of it was deleted and after this I cant trust her words even tho I want to desperately be with her again.
Am I normal for breaking this uo and not trusting her after all of this ?
Thank you in advance to everyone who takes this seriously and replies. I tried to make it as short as possible even tho there are more details. If anyone wants to know more feel free to ask.
