Help me out.
Here's the thing: I've been dating this one girl for a year now. We're both very young (I am barely an adult, she's not even an adult yet), but I do love her very much. I am from Europe and currently am an exchange student at a US university.
This summer (2009) she came to Europe with me and we basically lived together for 6 weeks. The last two weeks were not a pleasant experience - we were getting tired of each other a lot, and I messed things up quite a bit. She left being pissed at me. She left around August 15th.
In September 2009, I was starting as a freshman at the mentioned US university, about 3 hours away from the city where she lived. She's still in high school.
Two weeks after she left my country, she called me and asked me if it'd be a good thing to break up now. I kind-of agreed, so we broke up, basically. But about 3 weeks after that, I realized how much I loved her and wanted to get back together, so I talked to her again. She said we'll talk when I arrive in the US (this all is still going on while I am in Europe and she's in the US). My arrival date was September 19th.
When I arrived, she picked me up from the airport, and we decided to be in an open relationship. That was her idea. At that point, we were at her house. Later that day, her mom took me to my college place. That evening, my girlfriend called me and said that she didn't want to be in an open relationship with me, but she wanted to be exclusive.
Now comes the part where I really messed up - I said I didn't want to be exclusive because I wanted to have sex with other girls (at that point of time, my gf and I had had no sex). She was heartbroken. She even burnt a teddy bear I gave her. I know I am an asshole. Bigtime. Even worse, she called me the next day to ask me if what I said is what I meant and I said "Yes". I'll never forgive myself for that.
I really love her. I apologized 1000s of times to her and she said she accepted the apology. We decided to get back together officially on Halloween.
But, there is a problem.
I asked her "Have you kissed anyone while we weren't dating?" and she answered yes. Which is okay, because I've done the same thing. However, that guy lives really close to her and she admitted she thinks he's very cute. He's also an exchange student! Although she says she does not like his personality (he's kind of gangsta), she still thinks he is cute.
There's worse to come... Her parents will be hosting him starting January 2010. He will be literally living with her for 6 months.
I've been acting like a 14 year old lately... I've been calling her every day, texting her every day etc. which is what we haven't done before. I just got off the phone with her and she said she was in a nearby city (close to hers, not mine) with him, buying some shoes.
Now she says she won't try to date him because she is dating me. But I am not sure whether I know her anymore. For example, she didn't drink while we were together (because I don't drink), but since we broke up, she got drunk twice - with that guy.
She is acting more or less the same towards me. We still feel comfortable around each other etc. However, when I asked her if she loved me, she answered "yes", but she implied it was not as much as before.
So, kind folks of LoveForum.net, I'd like to ask you a couple of questions:
1) Do I have a reason to be afraid that she will dump me?
2) How do I make her forgive me totally - I just want the things to go back to the way they were before? How do I explain it to her that I really do regret what I have done?
3) Should I apply the standard "guy" tactics - kind of ignoring her, etc? (that'll be very hard, but I think I can do it)
I really thank you a lot in advance. Please be honest and truthful.
