If he did the 'dirty' on you? Then suddenly he realises how much he wants you in his life and says 'I didn't treat you well enough then but I'm willing to now'. Then has dinner with his ex gf (once) cos she's 'just a friend'. And he fucks off on stag do's cos he thinks you'll be ok with it cos apparently you can trust him now.
But you can 'tell' he has changed for the better deep down.....
