Boys who don't take the initiative with you really don't like you.
If you like a boy, your communication and getting along with each other has always been your initiative, and no matter how you hint and express, he has never taken the initiative once, and he always ignores you, don't doubt it, he just doesn't like you. It's not that he doesn't have time, it's not that he doesn't look at his phone, and it's not that he's shy and inexperienced.
He just doesn't like it and doesn't want to waste time pestering you. For people who are not interesting, silence is the best rejection.
A boy who only has an ambiguous relationship with you but doesn't find a relationship with him never thought about starting with you in the first place.
He may like you a little, finds you interesting, and wants to talk to you.
But he didn't have the idea of really trying it out with you.
Even at the most intense moment of ambiguity, he posted you on the circle of friends, shared his playlist with you, and told you a lot of things close to the cut-off point between boyfriend and girlfriend, making you mistakenly think that he seemed to be serious, and your relationship was finally going to be clear.
But when he turned around, he smiled and told you that he just regarded you as a friend to talk to.
Every time you fall, he's incredibly sober. 
Don't believe in the boy's promises, but believe in personality and character.
Promises are the lowest-cost flattery and pandering, and the moment they say it may be true, but when they say it, it's over, without any credibility, and even he himself will forget that he said such things.
But you have to believe in personality and character, and believe in what you know and know about this person earlier.
Don't listen to what he promises, but what he really does.
Don't listen to how he apologizes to you and asks for forgiveness after a fight and anger, but how he treats you when he has an emotional breakdown.
The lowest place of conduct is the best way to see a person.
Boys tend to weigh the pros and cons more than girls in relationships.
When you are thinking about whether he is handsome, smart or not, whether he is capable, and whether he is mature and stable enough, he is also thinking about whether you are beautiful, gentle or not, what the economic conditions are, and whether you can bring him value.
You ask him to be emotionally stable, and he will expect you to be sensible and considerate.
This is understandable, everyone is an adult, and they are evenly matched with each other to achieve the effect that one plus one is greater than two. You're good, but I'm not bad either, and we're just the right fit. 
Boys enjoy the feeling of being dependent, but they don't like to be overly dependent.
When you put all the focus of your life on him, he doesn't feel honored and happy, but feels stressed and suffocated. He can be the bottom for you and be your support, but he doesn't want to push you all the time, it will be tiring.
Rather than relying on him all the time, he wants you to be independent as well.
When he doesn't stay with him in time, you can go a long way alone.
Although I don't say it explicitly, in fact, boys are also very concerned about girls' sense of boundaries.
When you are intimate with other people of the opposite sex and laugh and make a fuss with them, he will also feel a little uncomfortable.
He won't cut off your social circle or forbid you from associating with other boys.
But he wants you to be careful, draw a good line, and don't go off the rails easily.
No boy is so generous that he doesn't mind his girlfriend frowning with other boys. Since you chose me, don't give others the same chance. 
Euphemistic persuasion is fine, but direct preaching is not.
When you feel that he has done something bad, you can give him euphemistic suggestions to make him pay attention and improve, but you can't preach to him. Replacing accusations and criticisms with understanding and persuasion will be twice as effective. When he does well, you praise him, and next time he will be more attentive and focused.
Otherwise, how can everyone say that a man is a child until he dies. He's a child, and you have to treat him the way you treat a child.
Boys who are prone to lying and betraying their nature, no matter how much they like it, don't get close.
It is very difficult for human nature to change completely overnight.
Today he lied to you, hurt you, betrayed you, tomorrow, the day after tomorrow, the next time, he will do the same.
The adult world is only screened, not educated.
People with wrong minds can't be saved or kept with no amount of love.
Boys also need a sense of security and companionship, and his efforts are not taken for granted.
He is kind to you, understands you, tolerates you, and endures you, not because he deserves it, but because he loves you. He wants you to respect, trust, understand, and love him equally.
Or at the very least, don't take his love for granted, slighten and trample on it at will.
You can not love it, but don't take off the powder and step on it back.
No one is perfect, don't love people according to your imagination.
Even if it's the other half you think is invulnerable, when you can't see it, it's like the shadow of the leaves cast by the sun. So don't expect someone you like, your boyfriend, your husband, a superman who can do anything.
To see whether a person is worthy of liking, the important thing is not whether he is a superman himself, but whether he is willing to become a superman at a critical moment for you after being with him. Instead of indulging in what you imagine him, get closer to and know the real him.
To love someone who is concrete, figurative, and genuine.
