You leave someone because you're afraid to hurt that person. It may be just that it's a convenient excuse to run away from your responsibility. If you know that you cant handle it, dont start. Then again, you'll never know that you can handle it until you start. The best way to go about it is not to give up. That's why relationships broke off, business fail and goals aren't met. When it is convenient, we LOVE. When it is inconvenient, we LEAVE. If someone has to leave because they love, it simply doesn't make sense for to love is to be strong enough to keep everything in order and to place it back together when things are in disarray..... not to leave.
