4. The man hides his exes
Our ex-partners should be left behind whenever we enter a new relationship. Talking about your past experience all the time is also wrong. But not mentioning anything from your past is not right either. You are dating a grown-up person and the older he is, the more experience he might have had. How much he hides may tell you whether his past relationships were successful or not. If the man won’t tell you anything, it may mean he has something to hide.
