This is the first question which lingers in one's mind after a break up - Isn't it? I often found myself thinking about this same thing.
Going over this phrase again and again in my mind when I wanted to get back with my ex desperately but wasn't sure if my ex wanted me back.
When you plan to get back with your ex the first question you need to ask yourself and know the answer for is "Does my ex want to get back with me?" Once you know this you can think of 100's of ways to "get back with your ex" - Which is easier once you know this answer.
You must take extra care to note your ex's behavior now - If your ex is sulking, seems depressed at time, gets irritated easily, looks low and dresses shabbily then you are in luck - These are sure shot green signals for you to make your move.
This would definitely mean your ex wants you back and you can rejoice.
Don't keep thinking "does my ex want to get back with me" or not.
Just keep working on ways to figure it out.
You can even know this if your ex is making excuses to communicate.
Your ex might call you or plan a meeting or simply "bump" into you at a pub.
These are all signals that your ex wants you back.
Once you are sure your ex wants you back, don't think any more and read up on tips to get your ex back.
