I'm sorry but the reality is you won't ever forget this...it's like saying how do I erase this sort of thing. You can only give yourself time and eventually the hurt will lessen. It's a choice really, you can decide to move on with your life and not obsess over the past or you can be stuck over something you have no power over anymore. I think these things happen for a reason...if it was meant to be you would have found a way for things to work out. It doesn't mean you won't ever love again and I think to deny yourself this sort of opportunity is rather self-defeating. Keep posting here, it can't hurt to take advantage of the support on offer. Members here will try and help in any way they can. Good luck.
