Jealousy is characteristic of men as well as women. Very often they literally go crazy when you are in contact with other men. Why it hurts them so much?
He is an owner by nature.
He doesn’t really want to share you with anyone. And this is explained, of course, by the desire to make you only him. It is difficult to condemn men for this, because it is partly determined by instincts.
He is afraid of competition
Every man, and a woman too, wants to be the most. But the presence of other representatives of the stronger sex next to you can seriously undermine his self-confidence.
He is afraid that will be worse
Not that someone will lead you away. But your colleague has a luxurious press, and his belly is hanging. And your friend from school has an expensive car and a high salary. He looks like a loser in their background, and he does not like it at all.
He is afraid of losing you
He really loves you very much. And the thought that you can happen to meet someone you love more than him makes him feel bad.
He has a reason
Or maybe he noticed in your eyes a real interest in another man? In this case, it is not surprising that the presence of competitors bothers him. If his jealousy strains you, try not to give a reason for it.
