You can ask your boyfriend to accompany you in your travel and see if he appreciates traveling as well. Try to convince him that he would miss the fun going out for an adventure while he's still young. There are things that he need to experience and explore. And you can return the favor - it's like introducing your world to him and his world to you.
I am travelling and left of the love of life at home. He is waiting for me to come back. Nothing will have changed when I come back. Our relationship will only get stronger with time. Distance is just distance when it comes to the heart so don't worry! X
I find it interesting that people say "nothing will have changed when you go back".
I can only speak for my self but I was a completely different person after traveling by myself for a year.
