Dear Mr. Freddie,

I've had the same experience as you do @this moment. But in different situation. I'm the lady n my bf cheated on me for almost 1 year.
I trusted him heartedly but in return he cheated on me. Well, basically the story is almost the same..
Now, intinya.. lho masih mau ama dia g? Kalo masih sih maafin dia n balik lg spt biasa (untung aja nnt kalo ujungnya dia g' lg selingkuh).. Kalo udah g bs maafin ya udah.. move on dude.. leave her.. let her has her own life..
N u.. get a life..
btw, I left my xbf n now I'm happy with my life while he's stucks with all kind of relationship problems.. :D

All the best!!
U know urself better..
