Should I travel abroad?

Yes definitely! My sister went abroad for a semester to Italy and she loved every minute of it and she wants to go back again. If you have the money go right ahead. It will make you grow and you will visit a new country. Its a win win. You gain knowledge and you have a good time in a new place. Also going abroad will help you become less shy and possible will learn a new language. Just do it and you will not regret it. And for you boyfriend I would recommend going on a break and if the sparks are still there when you return then you can just get back together. Take advantage and just do it!
