3SUM

My ex txts me, asking if I want to have threesome with him and a girl. I hate this guy since he left me for another girl, and we haven't spoken since. I was taken by quite a shock, so txted back saying no. But also was a bit curious on his recent sexual life, so txted again asking who he's asking me with. Turns out, HE WAS ASKING ME TO HAVE THREESOME WITH HIM AND THE GIRL WHOM HE LEFT ME FOR. Oh, yeah, I got tricked there, I called him and yelled and yelled. He hooked up with this girl after he dumped me, (he left me saying he met someone he'd like to go out with,) and they broke up after a few months, now she is coming back from wherever for a holiday shag, and they thought it would be brill to ask me. Oh, sod off, you are sodding lunatic psycho.
