<human>: Can you provide a brief rundown of the text in within 3 sentences?

My and my SO have been together for over 4 years now, we get along, and I love her. I've told her that I wanna spent the rest of my life with her. But she has some serious trust issues, and we've gotten into fights because I still talked to some of my ex-s. 

I gradually stopped talking to any of my ex, some of them were nut jobs which I didn't care anyway, some others were good friends that I simply ignored in order to make things easier in my relationship. I even closed my FB account (i can't say I miss it but still) 

3 days ago my latest SO (we never actually dated, we just went out and fooled around for a month) got in contact with me again via messages. I know my gf hates her so i tried to be careful so my gf wouldn't know who I was talking to. Yesterday I forgot to delete the messages on my cellphone and I got very protective with my phone, which I never do. My GF noticed it and today while I was busy getting ready for work I saw my GF browsing and checking my phone supposedly looking for a song or an app, then I took it from her and she got really serious and gave me the cold shoulder the rest of the morning.

I'm 90% sure she saw the messages with my ex which were absolutely SFW and friendly. And, to make things worse, we've talked about this before, and she did something like this when we started dating, with the same girl (one of the reasons I stopped talking to my ex in the first place).  Also, when she sees me messaging she asks me on a naive tone whom am I talking to. I don't like to make her feel bad or give her reasons to suspect anything but I don't like to be told who I can or can't be friends with. 

I totally get her point, and I can relate. But for her, there is no compromise. And I'm tired of the same discussions and right know I am on an emotional swing from worried about our relationship to really mad at her for spying on me.

Has someone being on the same spot? and how did it turned out?
<bot>: Ex got in contact with me after a few years, current gf checked my phone (which may have done before) and got passively aggressive with me. How have you dealt, or would deal with it?
