In the total sense, absolutely. Your past experiences greatly inform your mindset and mold you into who you are. No one meets anyone they’re serious about getting to know on any level and says “Tell me all about yourself, but exclude the past.” It’s asinine.
If we’re serious about getting to know one another, I need to know what your relationship is like with your family, I need to know if you’ve dealt with abusive relationships before, etc. This will help guide me in effective communication. It can also help me discern red flags.
If we’re talking body count, I’ve never asked a chick “how many guys did you sleep with before me?”. In terms of assessing her character, there are many things that are going to give me the decision-making data i need without asking that exact question.
