TLDR...

Me and my ex fiancee split up nearly 6 months ago. I wanted to get back with her for the longest time. I've had a threesome with her and her best friend (two in three days). Last night she told me she fucked another dude the night before (as did her friend).

What do I do?

The "fun" has begun with her and her friend, but now I know what they can do when together on a night out.

I also wanted to get back with my ex so bad until now, so what do I do?
