Sounds like you're still pretty down. From my perspective at least, it's a lot easier to stay "up" if you detach as well as possible, keep yourself busy, and focus as much as possible on getting a life, that includes hanging out with friends.
I know what you mean about weekends being bad, but that's the time you definitely have to keep occupied, even if it's only with housework.
Remember that if you give her the space that nothing dramatic is going to happen overnight. She isn't going to just forget about you. But you need this time to develop the detachment. Get happy with your own life and things will fall into place a little better, even if it's just improving your sanity.
I don't know about the e-mails. I concur that there may be something there, but it doesn't change the fact that you both need the space. Give the "miss you sometimes" a little more time to grow to missing you frequently.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
