Just play it cool. Unless you're still in love with him, you should move on with your life. Things change. The only constant in this world is change, or so they say.

He may have kept his promice not to look, but if someone started flirting with him he may have responded to it. He may be hiding that in an attempt to spare your feelings.

This is really giving him the benefit of the doubt, but I figured he is a pretty decent guy if you are still friends.

Now that he is not your boyfriend it is up to him to tell you. If you let him know that honesty is more important to you then your feelings on the matter he may be more ready to "come clean".

Sadly, if he does not want to talk about it because it is personal that is within his rights as you aren't dating any more.

The truth hurts. We are self preserving and as such we will lie to keep ourselves from getting cought, We dont want to look like we are week so we lie. He has moved on . His intrest in other women shows. If you plan on remaining friends update the rules of the breakup.If keeping him as a friend is so important than why did you break up. Expecting someone to remain faithful to just a friendship is asking alot. Now if you change the rules modify them for yourself as well. Keeping truthfulness in the friendship will make it stronger. Why do you care if he sees someone else? would he feel the same if you met another guy?

The good news is, you're moving out. The faster, the better.

I think you have pretty unrealistic expectations. He is being nice by trying to hide it, so it doesn't hurt your feelings. Really though, he doesn't even owe you that. You're his ex-girlfriend. You no longer have the right to dictate if he speaks with other women, calls them by nicknames, flirts, or even sleeps with them. He's a single man. Friends don't tell friends not to date. Let him continue to try to spare your feelings, and consider it an act of friendship that he is trying to be discrete.

If you must be open about it, I would suggest telling him that you're hurt by his actions, but also that you no longer wish to continue this petty "no dating" rule, because you recognize that he's allowed to move on. The speed with which he did so may sting, but you can't fix the situation by being controlling and trying to make him feel bad. He's moved on. If you can't be okay with that, move out!

If it does not help to confront him why do it? If he's moved on you should too. If possible I would move up the move out date, because sooner late he will be wanting more such as talking on the phone with her and that will hurt much worse.

You could begin looking for a 'new friend' your self BUT it is foolish to do so. You need time to heal and get back in touch with your feelings. Pretend it does not bother you that he is doing this, and for goodness sakes hold your tears until you are out of sight. To cry in front of him would give him satisfaction and he does not deserve it.
