Search Results: asking if he''s taken

I've been in a relationship with this girl, Amy, for the last 3 years, a month ago we moved in together, we love each other.
A week ago, i wanted to surprise her, so i took a flight to her hometown to buy the salt candies she used to eat when she used to live with her parents cause it reminded of her childhood, after that, i bought some flowers and took her to a movie and cooked a meal for her.
Everything was going great, but when i gave her the salt candies, she started crying, telling me "she doesn't deserve me"
Then she told me she kissed her ex in her office 2 days ago.
I died inside that day, i ran away from what it used to be our home.
She kept calling, texting, showing up at places where I'm staying, asking me to let her explain herself. Her explanation was that she made a mistake, she used to love him, but she loves me now. A part of me wants to trust her, but how can i?
It's been 10 days, i wanted to marry her, but now I don't even want to see her. I don't have any friends, maybe that's why I'm here.

I want to take another vacation coming up. I plan on giving a months notice. Right now it's been 1.5 months since my last vacation but it will be 2.5 months by the time it gets here. We have to use our vacation by a certain time or we automatically lose it. We still have time before that happens though. I still kind of feel ridiculous asking for vacation again. It kind of feels like I just got off of my last one in some ways. I feel like a lazy employee in some ways. Like my boss is going to go, he wants vacation again? Is this just ridiculous, over worked American culture that has me feeling bad for taking vacation time? I feel guilty putting in a request.
