Well that explains her trust issues, but that is something she needs to work on for herself and to not take out on you. It’s very, very important that you are assertive with her if you do get back together so that she understands that you are not them and that treating you like you are not worthy of trust because they weren’t isn’t okay. You should not have to be punished for what other people have done to her, and her snooping and acting like you are untrustworthy is basically a punishment.  So be assertive with her on that… that’s something she needs to fix to have a healthy relationship with anyone, especially someone who IS trustworthy, or your relationship is bound to fail later on anyway if she keeps that up.

We can’t help how we feel, but just try not to feel too bad because you really didn’t do anything wrong and I don’t really know what you could’ve done differently. I’m sure, when she’d asked, if you’d remembered talking to him that one time during the 2-month separation from your friend, you would’ve said that, right? If so, that was an innocent mistake on your part and it’s important that SHE be more understanding, too. And it’s honestly a petty thing to get mad about anyway and she should NOT have been snooping through your phone.

Just give her time though… hopefully she’ll realize (or one of her friends will and will point it out to her) that she is in the wrong here… but again, it’s important that she fixes her trust issues if you guys are going to have a successful healthy relationship.
