My g/f of 4 years and I recently broke up.
Honestly, there's not much you could say/do that would make him get over it faster. It just goes away with time... at least, that's how I was. I was always hanging out w/ people after our breakup and most of the time I didn't feel like being around anyone.
I just gave lots of time to myself and played World of Warcraft a LOT
At first it's hard to get used to, especially after all that time together, but now, I'm glad I'm single
I can do whatever the hell I want and don't have to worry about anyone else, haha.
So, hm... I guess you can kinda tell him that after a few months, he'll be very very happy and that it will all make sense then, but yeah, 3 months ago, I don't think there was anything anyone could've said/done that would've made me feel ANY better.. short of winning a million dollars or somethin
