What does it mean when a man tells you about his past relationships?
As I mentioned, sometimes speaking about an ex can be a way to challenge a woman, push her away or bring some form of closure. It can also be something a little bit in between: a way to slow things down a little. A man may mention his past disappointments and broken relationships as a way to pump the brakes slightly.
Is talking about past relationships a red flag?
If your date is talking about his/her ex or if the relationship has recently ended, this is a red flag. In order to be fully present with a new partner, there needs to be completion (some call this closure), a grieving period and a time for re-establishing the "single self" before moving into a new relationship.
What does it mean when a guy opens up to you about his troubled past?
If they open up to you it means you are sympathetic, warm, non judgmental type of individual with whom they would love talking about their life. It means he is willing to share his intimate thoughts and experiences, and to show you his real self. It is a demonstration of trust.
Why does he tell me about his hookups?
He could be unsure how you feel about him, wants more attention from you, or is just a little bit immature. If he's trying to make you jealous by talking about another girl, it's probably going to be accompanied by other obvious signs and behaviours that show his overall aim is to try and get a rise out of you.
