<human>: My LD boyfriend (20M) and I(18F) have been dating for two years. He lives in NY and I live in Sweden. We only see each other for two weeks twice a year.
None of us have currently the opportunity to move somewhat closer, and that wont change for a good 3-4 years.

The first year of our relationship was extremely good, we talked all day, everyday through texts and phone calls. Once the honeymoon period passed, I became slightly distant. I was very busy with school and hardly made any time for him. After he came to visit for the summer a few months ago everything was back to perfect again.

Now, once again, I feel like I'm unintentionally keeping my distant from him, I don't answer his calls or his texts. I spend a lot of time with my friends and I've been going out a lot more. I feel extremely confused and lonely, and I don't know if I can keep on carrying this relationship out, even though he is my first love and I love him more than anything else.

I don't want to give up on him even though I know I'm just hurting him even more by not getting back to him. I've never been happier than I am when I'm physically with him, but the distance is slowly killing our relationship, and I don't know if I'm strong enough to keep up with it.

Summarize the given text in a few sentences.
<bot>: Dating my boyfriend in NY from Sweden for two years. Distance is killing my feelings and our relationship. What do I do? Is it worth it?
