I have known him since 12 years, he is my class but since a year we became best friends. Even he isn't my type, I loved him because I was alone and he showed me that he's interested about me too but he didn't say any word. When we are alone he appreciates me and acts as lovers but with friends he stays acting as a friend -just friends-. But after the summer he became another person ...

he avoided me and he loved another girl but he didn't tell me about that although we are so close. After they broke up he returned to me like the old times. When I ask him about the reason of his reactions he told me that he doesn't know why and he won't do it again. At the time, and as the old times he is acting like lovers again when we are alone and he always finishes by saying he's stupid and he did that because we were alone in the same room. What can I do with him because I am not sure that he loves me too because he never said it.

Dear Farah,

It seems that there is nothing between you that could be called a real relationship. And he doesnt seem serious. Let things slow down between you two, and leave it at being friends.
You should get some space to meet other people, and let the options be open.
