Why do guys think their ex story is OK on a first meeting? Sounds like they are trying to explain why they are single and why they are not worthless because they were capable of a great relationship. Trouble is they sound stupid. If their gf left them after years there must be something wrong and that could be a warning sign not to find out the same thing the same way!
Give an the elevator pitch not a sob story. I’m not your mate at the pub. That’s probably why she left! Get a life, don’t try to hijack mine, I am not interested in your life story, I want a good time with an interesting person who could be going places, someone who might care for me along the way. Tell me what you will do for me to win me over, not what is wrong with you. And stop wasting my 5 minutes!
