Most Helpful Girl
It's painful discovering you've been used. Most of us have been in that position before. Experiences like that make you wiser and stronger.
You become wiser in the sense that you see the signs early on with other people are are potential "users " , and you become stronger in the sense that you let go of the person, as soon as you see those signs. We all live and learn.
If someone uses you, then it's a reflection of that person's true character, and you trusted him or her much more than they deserved1
