How to adopt culture?

I met this Polish Guy, he is so tall (191 cm) and me was like (150 cm), we are happy talking and being together but time comes i asked him about marriage thing, he told me that he is not ready and he wanted to enjoy life. But we don't have a relationship, we are on the Mutual Understanding part, missing each other and hugging. As time goes by, my feelings for him growing deeper and i know those feelings are nothing to him. Please advise me on what to do on this case. Do i need to continue on this friendly relationship? I knew he felt what i felt.
