Firstly, im sorry that you are hurting over some loser who really doesn't deserve your tears.
But in answer to your question, probably the same reason you'd take him back right now if he knocked on your door and begged for forgiveness. (Im only making an assumption that you want him back from your question, sorry if that's not correct)
The reality is that sometimes when someone hurts us by cheating, although you know it's not your fault deep down it can build up a feeling of insecurity and make you ask yourself questions like "what's wrong with me? Why doesn't she love me? Is he better then me? Could I have done something different to make her stay? " most of the time it isn't about being in love with the ex so much as a morbid attempt at making themselves feel wanted by the person who rejected them and hurt them by cheating.
I suspect that having a long distance relationship made it easier for him to (stupidly) forget how he feels about you and when the opportunity arose for him to heal his wounded ego he took it.
He's a weak minded $#@*hole who doesn't deserve you.
And I'm sure it won't be long before his old $#@* cheats on him again and it wouldn't surprise me if he came a knocking back on your door.
If I were in your shoes, I'd slam the door in his face.
You really do deserve someone who will be as loyal, faithful, honest, reliable and respectful as you are. Don't settle for less.
They are the losers in this situation, he's lost a girl that respected him in every way and gained a tramp that likes to open her legs a little too frequently to multiple people.
Best of luck to you and I hope you can move on and forget about this douche bag
