If you want to know who somebody is, focus on what they do every day, what actually fascinates them, and how they behave around people. That will show you in which direction they want to go. The sooner you gather the strength to accept the truth, the better it will be for your future. Stop with this selfish charity. If you have so much time and energy, put it in your life and find a stable person who wants stability in relationship too.
