So I met him online on tinder recently.. We met and It was all clicking - he brought me a rose, we found much common interests. Even after the date he kept talking to me that he likes me and he hopes that with our friendship it is going to lead to something deeper. Until a few days when he started acting bit more afraid and cold. He asked me to go to his place, we had sex a few times. We match on some high level - both into medicine, poetry, video games, sweets, gym. But when i tried to bring out the relationship topic, he said that he is afraid of relationships because his heart was broken in Med school and it was hell for him to concentrate on the studying. He said maybe in a few years. I'm so into this guy. What should I do?
