Important note: Through out all of this, never make the girl feel that you still want to be with your fake ex.
Let her know that you just can't help feeling jealous, considering how long you were with her (she will empathize).
Read the following and you will never again have problems hooking up with the opposite sex.
If you're a guy and looking to score, this will take a little more reading than the above section for girls.
Once you've joined, use the easy to use social media setup to find people near you who are chasing the same fantasies.
