I, in the past, started seeing somebody behind my girlfriend's (at the time) back because I had caught her cheating on me (to which she admitted to it) and she threatened suicide if I broke up with her over it. She later broke up with me (the girl I was seeing didn't pan out) before coming back months later downtrodden (but not crying) that she had a miscarriage of guy who she broke up with me for's baby and asking for me back.
