What should she do: to keep up or to give up?

She met him in a foreign country where they both were volunteers. She had been there for 3 months before he came. She wasn't interested in him at the beginning even he was always cheerful. She was tired with her intensive work, and she was homesick as well.

A few days after his arival, he asked her out for a coffee break. They talked and she found him nice. Then he asked her to go to cinema. She didn't want to go but he said he really wanted to see that movie but didn't want to go alone. They had a nice time in the cinema and he held her hand when she was frightened by the movie.

They got closer and closer afterwards. They went out every evening after work for dinner of for a drink. He cared about her all the time, and she felt comfortable to be with him, particularly after a long day working. He delighted her life there.

Eventually, they kissed each other and said "I love you". Then it was time for him to leave the place after 2 weeks being with her. He travelled around the world and went to another country for another voluntary work. She couldn't go with him because she had her own mission.

They have kept in touch but she thinks he doesn't love her as much as before. He doesn't call her nor write her as often as she does. His words for her are not as sweet as hers for him, even he said: I ALWAYS think about you, pray for you everyday. That's exactly what she does everyday: thinking about and praying for him.

He will return to his country in one month and it will be easier for them to talk but at the moment she feels empty. He hasn't planned anything which includes her. She seems not in his future. She wants to give up because she doesn't want to be hurt or disapointed. But part of her wants to keep up this relationship. She's afraid that if she doesn't do the best to keep him, she'll regret later.

However, she's not very sure if she's really in love with him, or she just wants what he can bring her. She considers him a sensitive and clever guy. He's sweet and he alone in this world makes her happy.

She lives in Asia and he's from Europe.

What should she do???
