I'd really appreciate Some Help

So here is my situation. I'm a 19 year old woman at university in the city. My boyfriend didn't have the grades or the money to come here with me. After a lot of discussion we determined we would stay in our relationship even though we were far apart. We've been together for over two years and decided not to let this be the end of us.
My problem is that I am very shy and don't make friends all that easily. But I did meet one person, a guy. I was an aweful firt when I was around him. I told him about my boyfriend one night when he asked me for a kiss and he never asked again but made it clear on several occasions that he I could kiss him. I told my boyfriend about all this. He was upset. He asked me not to see the other man again. But I promised him he had nothing to worry about.
That was a lie, I eventually gave into the other man. We kissed for hours.
From here I don't know where to go. I am afraid of being alone. And I don't want to hurt my boyfriend. But without this other man I will be alone here in the city. Back home me and my boyfriend share all the same friends and I doubt I would get any sympathsizers.

Its usually a bad idea to go off to a university setting with a boyfriend because you tend to meet ALOT of appealing people there.

As far as this circumstance goes, you have a choice to make.

You have to decide if the relationship you have now is worth sacrificing for the guy you just met. If it isnt, then tell the guy you just met that you arent looking for a date. If he KNOWS you have a boyfriend, I would choose your boyfriend over him. If he's willing to cheat WITH you, then hes willing to cheat ON you.

If you decide to stay with your boyfriend, tell him what happend and that your sorry, it was an isolated thing and you feel bad.

As I said, I would reccomend you stay with your boyfriend now, but the choice is ultimately yours to make.

I think you need to take this opportunity to make the college experience better for yourself. You don't HAVE to be alone and have no friends - you are choosing to. I totally understand being shy, but each university has a counseling center that offers individual and group counseling and you could work on your shyness and increase your ability to make friends. College is the easiest time to make friends, and this is the perfect environment to learn, and the best thing is - the counseling is free on campus.

So don't just think of your current boyfriend or your kissing partner as all you have - empower yourself and help yourself meet new people!! I know you can do it!!
