Think, what if you didnt find out? Then you wouldn't know and he would continue to cheat on you. So my dears you let this fellow go because if he really cared about YOU he would never even dream of another woman, but obviously as you can see here, he doesn't take the relationship seriously as he thinks "Well it's a long distance relationship, she won't know". Don't let him think that, if he is thinking that (which it seems like he is) let him know that it's not okay to wander off with other women! If he really wanted it to work, it could, as you know long distance relationships don't work well because the other partner gets paranoid or suspicious (though not always true) and they end it on those terms! But don't get scared, these relationships can work, just as long as you BOTH commit to each other 100%, there is no way in being sure whether he/she will be faithful that's just based on trust. But in your case looks like somebody couldn't deal with the pressure. I say this guy is better off alone. He don't deserve a good person like you. Good Luck.
