Let's first be clear about what you're asking. You want to know whether you should put your love life on hold for someone indefinitely without knowing how they feel about you. Phrasing it that way, doesn't it seem more unreasonable for you to do that?
People wait for lovers for a variety of reasons. Some reasons are better than others. Examples include one partner moving away due to a job, military deployment, schooling, incarceration, etc. Alternatively, one partner may be married or involved with someone else.
The couple stands a better chance if both partners are firmly committed to a plan for getting together. However, you haven't expressed your desire to reunite. Before waiting, you might want to do that at least and determine how long you will delay your happiness on someone else. You also need to decide whether waiting constitutes continuing to date around or being completely out of the dating game.
There are many people out there who could potentially fulfill your happiness. I don't understand why you'd want to go "all in" by putting your life on hold for someone who doesn't know you're waiting. You deserve better.
