Don't do it. That's the mistake people make cause that just turns in to trauma dumping. Instead, have conversations about what's in the present. Leave the past out of the conversation until you're sure that relationship is going somewhere and you're both on the same page. Ladies....tell him all I just stated and see how he responds. The only things you should discuss from the past are any possible STDs, criminal record, or not, spiritual practices and morals. NEVER speak about your exes, and never in a bad way. KEEP the conversation in the present only mentioning a few long tern or short term goals.
