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

I don't really know how to begin this, but all I can say now is that I really don't like the fact my boyfriend still talks to a girl he was after months ago before we started dating. yes they're friends, but I don't like it. Have I expressed my opinion? no. Only because he's the combative type and will come back at me saying I talk to my other guy friends.

Also, we have been dating for 8 months.

However the difference is not only have I actually stopped completely, but I basically dropped of the face of the Earth and don't respond to them. Not only that but I make him aware of if one of them is trying to contact me in any way, shape or form just so he knows. Even the creepy co workers I have to deal with. He knows everything that goes on in my personal life. 

The reason I quit talking to all of my male friends was because he told me about his past exes and how they'd go off and hang out with their guy friends and cheat on him. Do I believe him? Of course. I have no reason not to anyhow. I respect his opinion enough and I really care about him and his feelings.

How I found out was just by glancing at his monitor from time to time, just out of curiosity of what he would be looking at. That or he would mention he has to send something like some kind of unimportant picture or message about nothing to this girl. He's glued to his phone 24/7, even when we're having alone time and I can't stand it. I definitely can't stand that it goes off most of the time we're hanging out.

My mood definitely changes when he mentions anything about her and he knows I get mad or upset, but he can never figure out why. I just come up with a bullshit excuse that I don't feel well. Why do I lie about this? Because I don't know how to really tell him how I feel. 

People of reddit, what do you guys have to say about this? I need advice. This is only my second relationship.
<bot>: BF still talks to girl he was chasing months before we got together. I'm uncomfortable with the situation even though she is in a state miles and miles away with no chance of ever coming back. What should I do if anything?
