-You should be the one to dump them first. People who dump instead of getting dumped feel much less pain and can get emotionally balanced in a much shorter time compared to the people who get dumped who are left with a severe trauma for a veryyyyyyy long time.
-Do not stay in a relationship for more than 5 months. Beyond that time, the more you stay the more you get hurt, so just leave after 5 months and find someone new.
-Do not allow yourself to get emotionally attached to anybody, this way if the relationship would fail, you will not suffer as much as you would if you were emotionally attached
-Looking for a true love? Rent a couple disney movies, true love could be found only in movies, this is the real life
-One thing that i actually found useful (Did not belive in it before), follow astrology, it is not accurate 100% of the times, but it could give you a pretty good idea of who you are and who you are looking for, and who should you date.
you are welcome to add anything of your own, whether its something you have learned or something staritic and funny about relationships that you came up with.
