<human>: I'm happy with my life and I'm in love with my SO, but I've never fully gotten over my ex...Until this very moment. I don't have a facebook, I loath fb, but today I made one. 

Like I said, I never really got over my ex, the moment I told that person to go to hell I never saw that person again, never had any sort of contact with that person for over the last two years. We don't have any common friends so it was really easy and the fact that I've never had a fb made it easier to avoid this person..However, this always left me with a 'what if' kind of feeling. What if we had stayed together, what if this person hadn't cheated on me? I mean, I spent four years with this person so I guess it's normal to wonder right? 

So today I created a fb just to find out what happened to this person..Yes, just to stalk them. And turns out the ex married the girl that ruined our relationship (the one ex cheated on me with). And while looking at them and how happy they are it occured to me..I would never have been that happy with the ex. I never was that happy with the ex. Even if no one cheated we would not have been together today. 

Ha! I'm free, no more wondering what if. I know now. So Reddit when did it hit you that you were indeed over someone you thought you could never get over?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Four year relationship ended due to ex cheating. No contact for 2 years and always wondered what if. Found ex on fb and found out ex is now married. No longer wondering what if.
