I'm sorry to hear about your break up.
*insert inspirational speech about 'her not being worth it', 'there's lots of fish in the sea', 'you're better than her' and/or 'if it's not meant to be, it's not meant to be' here*
Or watch this video.
(Hopefully you smiled/laughed at the above comment and/or video; otherwise I'll feel like an insensitive prick)
On topic, while I think using the time machine for personal gain is tempting, I'm going to have to decline. As said by another member, the choices I made in the past directly contribute to my present state. If I corrected all my mistakes, that wouldn't be 'me'.
If we're talking about using the machine to prevent a disaster, I'd be a little more inclined to take advantage of the space-time continuum.
