of course there is away to Get Her Back.
but why would you want to, becasue its easy? becasue shes hot?
is it really worth the hassle simply becasue you are scared to get back into the game. its a daunting prospect to go out and pick up someone completly new, especialy if you jsut had someone, but its definitly the hting to do my boy.
go out find someone else.
on a side note, if you didnt like that answer, bare in mind my friend, that doing this will make her want you. stay friends with her, say "maybe you rushedthigns" but dont arrange to meet up or have sex(and i mean that last bit) if you make it too easy to get back together you will be all hers.
- go out find someone else or at least flirt and have fun
-stay friends with her, dont tell her about your exploits persá but certenly let her know your having fun going out without directing it at her.
+ the knowledge that what she did was wrong is on her mind, (if she truely believes it that is if she doesnt then really REALLY dont bother with her)
+seeing you happy and having fun will make her question herself as to how happy she made you, or how sad she made you, and herself in general
+never hurts to make people jelous, especialy if what she did was a "Mistake" but bare inmind women are not stupid, unless she was raped, she made a conciouse decison to have sex with her boss, anyone can claim"it just happened" or "one thing lead to another" these are things women say to appear less slutty to other women and men.
+make sure you keep up contact doing this will ensure she doesnt forget about you and leave the possibility for you two getting back together, all thesethigns will driver her mad and she will desire you to
"make up for what she did"
"to keep you to herself"
"to stop you from moveing on"
obvisouly if you get back together she will technically win, but by the laws of influense, making her do something that shethinks is her idea but which is actually yours is like the golden rule
"make it seam like her idea"
best of luck old boy! let me know how it goes
