When meeting someone for the first time you should try to be a good listener. Sometimes a man or woman will show signs of being controlling or some other negative behavior. Another red flag is a person who constantly talks about their ex. This is an indication that they aren’t over them.
You can judge a person’s character by how they treat others; waiters, etc. Being rude to other people is a sign that they’re not a nice person.
If a man is late to a date, and he hasn’t called or texted you to let you know and to apologize for his lateness, this is a sign that he doesn’t value your time, he’s inconsiderate and this will only worsen if you continue to date him.
