When a guy loves, he is faithful to you. He realizes that his feelings for you are more important than some meaningless intrigue.
He does not even think about treason, because you are the only person on his mind. In his opinion, you are the most beautiful woman in the world. With no exceptions.
If a man expects to spend the rest of his life with you, he does not think about flirting with someone on the side.
When he has no doubts about your relationship, he interrupts communication with "possible options." He mentions you in a conversation with others, makes it clear that he can be trusted because he has made a choice, and he is important to him.
If he is serious about you, the people around him know about your relationship. He tells about you at every corner and does not build himself a lone wolf in search.
He does not behave as if he is an enviable bachelor, and does not mislead other girls. He doesn’t waste time correspondence behind your back. He does not cover his phone when you are interested in what attracted his attention.He does not call his girlfriends as fake "friends" in his contact list. He does not translate his smartphone into flight mode so that you cannot reach him. He does not put the password on the smartphone, which is impossible to crack. He has no secrets from a person he trusts in everything.
If he appreciates the relationship with you, he does not think about other girls when he falls asleep next to you. He does not dress up in the hope of impressing handsome colleagues.
If he truly loves and respects you, he will not betray you either physically or emotionally. He will never hurt you, because you have everything he wants.
