Even if you may feel the situation with you and your ex is hopeless, it isn't. Take a look at
The Magic of Making Up system. It lays out a complete step-by-step plan
to "get my ex back".
If you believe you can get your ex back by doing nothing you will be sorry in the future. If one thing in life is worth fighting for then it is to get back an ex who you love and think is the right one for you. Nothing else in your life should matter right now.
