I want to travel abroad and not tell my girlfriend.?

We had a huge fight last weekend and I don't wanna put it up here. Basically she was wrong and got caught and my reaction was not the greatest I pushed her down the stairs. We kinda broke up for like an hour but then we've been together for 28 months, so we decided to work it out and start a better page. I'm happy that we are okay. But I'm still hurt with what happened over the weekend. I can't eat properly only today I actually had a meal. In simple terms I'm not happy at the moment.

I need to travel for a few days and be alone to think about things by myself and I don't want her to know since we are "good" again. Any good place you know that I can travel to UK or Abroad.

Please help!

Thanks in advance
