You need to talk to her about it. People should never touch other people inappropriately and what happens if one day you hit her and say "Oh well, I felt like it" - I can imagine it would be a completely different story and an absolute double standard. Talk to her or get rid of her.
To love is to suffer. To avoid suffering, one must not love; but then one suffers from not loving. Therefore, to love is to suffer, not to love is to suffer, to suffer is to suffer. To be happy is to love; to be happy then is to suffer, but suffering makes one unhappy; therefore to be unhappy one must love or love to suffer or suffer from too much happiness. I hope you're getting this down.
