for me, well I haven't gotten over her completely, I still think about her, but I'm beginning to forget her a bit what is good...
to answer your question, it's been a year since we split (so we don't really have the same situation, you and me) and it's been 6-8 months that I built my nerve to delete from my life...
Do I regret it? yes, but if I think to myself how I felt last year...I now know that I'm feeling much better now than before... I'm starting to forget.
It's sad, I know...love...when we have to go our own seperate ways because the other doesn't love us back, or whatever... to say goodbye and never see each other again. But hey, keep your chin up and know that you WILL find love again.
I'm not saying mine's been easy, I've drank a lot, eaten junk food, hey my health is plummeting so I've been depressed...not to mention, I'm a bit cynical now.
If you can say goodbye to her, well then what you need after is a distraction, something to occupy your mind, me, I watched all the 24 series with Jack Bauer and I find it to be great. I've also dide other things aswell...like video games...
You see dude, Our heart is like a baby. the "girl" or "guy" we love is like the newest toy in the store, we get it, we hold it, we cherish it... then when we need to say goodbye, the toy goes away and our hearts start to ache (or metaphorically the "baby starts to cry") the only way to calm the baby (metaphorically our heart) is to give the baby a distraction, something to quiet the baby down...(not another girl, but more like partying with friends, watching films, etc...)
My explanation is a bit complicated I know but it's still logical...
If you ever do it, well good for you, it's gonna eat you inside, and it's gonna be painful, just live your life day by day, don't think ahead, keep your head down and avoid things that remind you of her...baby steps first dude...
Peace.
