It's going to get better, my friend, but it always seems to take longer than you thought it would. (I remember people telling me that and thinking "WHEN?!)
I was devastated by my divorce, but now my life is so much better that I look back and shudder to think that I would have stayed together if I could have.
Use this opportunity to take an unblinking look at yourself, and make the changes that need to be made. Get your head together. Go camping alone, think and read. Get in shape, have your teeth whitened, whatever. Do some traveling to broaden your perspective. Don't be in a hurry, and don't smell like desperation. Make a concious decision to come through this with wisdom instead of bitterness. Be what you should be, and a better woman will find you eventually, promise.
It's a cliche, but it's a cliche for a reason: This isn't an end unless you make it one. It's an opportunity for a new beginning.
