If you’ve been wondering if you should go, then go. It doesn’t have to be forever. Take a break if that’s what you want. Don’t stay because you are afraid you won’t find someone else. If your gut feeling has been keeping you up at nights, you need to set yourself free and explore. Go and spend time with friends. Spend time alone if that’s what you need.
And if those roads lead you back to that person, then that’s great. Thinking if someone out there is better for you is enough reason to go. One way or another you will eventually wind up where you’re supposed to. Whether it’s with a new person or back into the arms of the person you left.
