It's just normal behavior and nothing else.
1, always pay attention to your dynamic, in fact, most of the boys and girls in love with a person when the performance is the same, when a boy is in love with you, will silently pay attention to you, when you send a bad dynamic, he will also take the initiative to comfort you, give you to rely on.
2, take the initiative to contact you, call you, if you really love a person, then you have to learn to take the initiative a little bit, otherwise the other side in the end do not even know who you are, this is the most pathetic, when a boy began to take the initiative on you, it shows that he not only want you, but also in love with you.
3, very easy to hurt, you may not know what you do, it hurts him, which shows that your every move can affect his emotions, also shows that he has put you in the heart, which means that he eighty percent is in love with you.
Extended informationFor boys, people seem to prefer the second point of view, the initiative to fall in love, which has become a lot of boys love principle, the pursuit of love a lot of ways, but if you mastered well, you can do twice as much with half the effort.
Paying their own time and energy, and then go after a girl with all their heart, a lot of boys will use this "send warmth" way to chase girls, although there is a certain effect, but often just for the girl's touch and guilt, even if you can reap the benefits of love, not necessarily capture the heart of the girl.
In the final analysis, this way of pursuing is often just moving themselves, only the low emotional intelligence will insist on doing so, and those smart boys, they not only care about each other, but also to do things right.
