What are signs of a cheating boyfriend?

I recently found out my boyfriend was seeing another girl while we were on a break. This "break," that i asked for, was only for space and not to meet/hookup with other people.So by no means was this a "break-up!"He later told me that he went on a date with this girl and that she spent the night, but ofcourse he said, "nothing happened."So, i felt it was honorable to come out and tell me so i dropped it and we moved on.
-to get to my punch line,After we ended our break, i asked him to cut all ties with this chick and even erase her number.So he did, or so i thought.Before he erased her number i secretly wrote it down. i know that sounds crazy, but i had to do it! One month later (lastnight), i dialed her number on his phone, while he was sleeping, and she was SAVED under some random # that he renamed to make it look like a work contact!The same "work contact" that has been texting and calling lately!I later called i her to see if she would have compassion and fess up, but no such luck

ok ok...listen to me...u asked for a "break" and there has to be a reason for it...deep down u probably know that this relationship isnt going anywhere...apparently he felt the same way cause he did not waste time to go and meet up with someone that spent the nite...they definitely did something that nite. no question about it... and for him to keep her number and lie to u that he deleted it then he is scum... u will be in a really bad heartache if u continue to go out with this guy..he will eventually pick her...so dont do that to yourself...be strong..end it with him for lying to you...move forward and u will see better come your way...

Oh man thats crazy!! I think you have to break it off before it gets too late. First off you have no trust in him. Because if u did u wouldn't be doing the sneaky things u are doing to spy on him. Once the trust is lost in a relationship things will never be the same. you will honestly drive yourself crazy trying to be ms. private eye. and im definitely speaking from experiences. good luck and i say its time to move on. there is always much better things out there for you.

If he is still talking to her there it is most likely that he still has something going on with her. I was in a long relationship where the same thing was happening. If he is not physically doing something w/ her, he is keeping the door open for it. I would come out and ask him about it. He going to get mad that you looked at his phone, but it's better to get it out in the open. Just remember the old saying, "if they will do it once they will do it again." It's true been there before with guys. Maybe you should move on & meet some one new. I did & now look back and wonder what I was thinking.
