In my opinion, before making any big commitment to a man, you need to go through these situations (feel free to add more in the comments), and evalute how he reacts.

1. The way he handles being said no to

Try it, refuse something, anything. It can be a date location or time, a certain activity you are not into, a TV show you don't want to watch...

How does he react? Does he pout? Gives you the silent treatment? Gets aggressive? Tries to guilt trip you? That's your cue to get out. If he can't handle not having his way in these trivial matters, how will he handle being said no to during sex? He won't.

2. The way he cares for you, when you can't

At some point or the other, you'll get sick, have bad period cramps or will break your arm...

How does he care for you when this happens? Does he make you food, gives you medicine, goes to the shop to get you something you need? Or does he complain about how much work he already has and what an inconvenience your incomfort is to him?

3. The way he handles stressful situations

You are all ready for your vacation and on your way to the airport, but you forgot your passport. Money is tight and you need to budget until the end of the month. He has an important deadline to meet for work.

How does he handle this? Does he panic? Does he scream at you? Or does he stay calm and solution-oriented?

4. The way he reacts to you (two) being in danger

You are being robbed. You end up in a shooting. A car is driving staight towards you. Some men got offended at the bar and want to fight.

Does he run away? Is he completely clueless about what to do? Or does he put your safety first?

5. The way he treats anyone in the service industry

People in the service industry are unlikely to negatively affect your life in the case you disrespect them, they just can't talk back to you rudely and rarely can refuse service. (I have been a waitress, customers can be the absolute worst.)

How does he talk to them? Does he respect them? Is he the same as usual? If he isn't, be prepared to see this behaviour become the one he will adopt with you once he decides he is "done putting on the show".

6. The way he talks about women, or feminism

What is his vision on women? Does he has female role models? Does he know of historically important women? Does he have an interest in learning? Or he is so disinteressed that he can't even watch a " female centered" movie?

Try it, tell him about this great movie you would like to watch (Hidden Figures, Portrait of a Lady on Fire...), is he bored after the 5 first minutes? Does he try to distract tou? Or does he take interest in what he is watching?
