<human>: My girlfriend and I have been going through a rough streak for a few months.  We moved in together and we started living our own lives and doing kind of our own things all the time.  She was always like this and I'm not usually like that in a relationship, but I adapted and started making my own plans all the time and filling the time up that I would normally have been spending with her if she wasn't busy.  So after a few months of not having a great time with each other we were both pretty done with the relationship but neither of us said anything.  During my time that I had started doing my own thing I started reconnecting with old friends, guys, girls, anybody really, and I started going out and meeting new friends.  So I met this one girl at the bar and we exchanged numbers and we were texting back and forth.  Nothing sexual really but flirty on my part out of boredom and because when you don't know much about someone the easiest thing to do is to get them to talk about themselves, so I start with something I like about them and get them to elaborate.  So about a week after I started talking to this girl my girlfriend and I got in an argument and she brings up my new texting friends name.  It turns out that she has suspected something and gone through my messages.  We talked about it, and I wasn't exactly being the best boyfriend because the texts were flirty, but there was nothing sexual there, so I don't think she was super pissed off.  But should I be mad that she went through my phone, or am I in the wrong enough that she was right to do so?  I would never ever go through her phone, whether I suspected something or not.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: girlfriend read my messages after months of neglecting each other and found flirty messages with a new friend.  Should I be mad or was I wrong?
