Maybe online dating and/or long distance isn't your cup of tea. Get a stats RS with someone you ain't attracted to and/or isn't attracted to you, and then maybe do some traditional dating-scene perusing.
Also you should probably get to know a person better before making it "official" as a relationship. 5 break-ups in 2 months means you jumping into a new relationship every 2-and-a-half weeks. That's no time to recooperate from the previous relationship, and very little time to actually get to know who you jumping into it with. What exactly are the cause(s) of each break-up, anyway?
Out of curiosity, are you covered 24/7 or is it like when you wake up and get dressed it's a live duckling suit?
