She's not worth it.

I wonder if she went for you as a rebound.

Rebound is so unfair to the anyone who will be doormat.

Calm down, confide with your friends and start afresh, new day 

It's very fair of you to explain that. Although I don't doubt that many people start a new relationship after a breakup to forget about the ex, there are actually many whom wants to make a new r/ship work. They may try hard and even try their best but sometimes things just wouldn't work out. They might run back to their ex-es which I think would be a better choice than staying in a new r/ship for so long until he or she hurts the other partner.

I have walked out from a r/ship of almost 6 years and have been single for more than a year. Never thought of getting a rebound because I believe love is like fate. You'll know when you find one. Don't force yourself to do something that you're unwilling because the outcome is not going to be a desired one.

I like how you'll wait for her at the cafe, but I can tell you, in this way, you're indirectly applying pressure to her. Making her feel bad that she makes you wait. But if she appeared (out of kindness), you might think that she still love you. It's a dilemma isn't it?

The best way to move on is to keep yourself busy. I know it's difficult to resist dialing her number. How about deleting the number so you can't press that dial? Control yourself and after a period of time, you'll find yourself moving on. Go out with some friends on thursday and don't go waiting at the cafe again.
