Kristina, there will be better times

Poor Kristina,
I saw your trip ending like this...

As did my trip in 2007 when I THOUGHT I was going to have this great, exciting and fun time with my then-boyfriend Daniel, but everything turned out to be an absolute disaster.
I texted Daniel when I got off the plane, telling him he could come over at 9 or 10 (I stayed at my hostfamily's house).
He was out with his old girlfriend to see a movie and "toooooooooootally forgot" I was coming that day (HOW???). He came by the next day to say hello and then leave. He came back 2 days later and we hung out for an hour or so. We went to the movies a bunch of times with some other people. Always with us - his ex-girlfriend Em. I like her just fine, we were really good friends in my exchange student year. But now that she kinda knew that I was dating her ex-bf, she was sooo mad at me. But she aparently always had to be with us. Of all these movie nights we had 1 night where it was only Daniel and I, I think.
My hostfamily went on a trip to Denver and I went to stay with Daniel. His parents, neices, nephews, 2 sisters and their husbands/boyfriends (who all live together in 1 house) where all very welcoming. First 3 days were awesome.We usually went to his best friend's house, Chris, and Daniel and he played some Videogame. We watched movies, too, but nothing fun.
Well, long story short, after 3 days, Daniel started to only come home to drop me off, then proceed to drop Em off and go back to Chris' house and sleep there. Sleep to him means going not waking up until 2 in the afternoon. I got up at 9 everyday and just sat around until he eventually came to get me. Only to go back to Chris' house and continue the videogame madness. My hostdad came back from Denver and we got a ticket for me to go and join the rest of them for a week.
One night, when Daniel did come back from dropping Em off at her house, it took him 2 hours for a 30 minute drive. Thanks Daniel, that wasn't obvious AT ALL. After 7 days at his house, he sat me down and told me (staring at the ceiling, not even looking at me) that he doesn't like me as much as he thought and sorry and bye. Then he left. To where? Well, to sleep at Chris' house! Left me with his family, who immediately saw what was going on and tried to help me as much as they could aka. giving me a cell phone to call my best friend in Germany for whom it was 3 a.m., poor girl. 6 minutes and then the connection broke off. No more money on the card.
Then I went to Denver, which was fun. I enjoyed being away from him a lot.
Back in Virginia, I spent the last days until the end of my stay with my hostdad and the spanish brother of my hostmom (my host-uncle, I guess).
Come as it must, my flight was delayed and later cancelled due to bad weather conditions at JFK in New York City. Grrrreat. We re-arranged my flight to a week later, because we had to plan for day when he was off work and went back home. One more week.
I spent it with sleeping, crying, more sleeping, eating and watching movies with my host-uncle Claudio. Daniel called the house asking if it was true that I'd stay for another week. Yes. He said he'd definitely come see me before I leave to say bye. RIGHT. Of course he didn't.

2 years of nothingness.

Then a message about 3 weeks before my next trip to the US. How are you, we haven't talked, I'm really sorry about what happened, I learned from that experience, I'm so sorry, I changed, can I have my friend Marie back. ..Ehh...yeah...
We're friends, now. We try.
We went to the movies twice and he took me along to lunch with his family.
3 weeks into my stay, he moved to Massachussetts. This time, he did come to say goodbye.
But all the feelings we once had for another came back when we met again and that was not good for either one of us.

All I can say is:
You'll learn to deal with the emotions. You'll learn to put them in a tiny box and shove them in the back of your mind. The only advice I can give you is -don't take them back out-. Serioulsy, don't. Put them away and leave them there, it's better that way.
