Even in marriage
husband and wife uses each other
so by definition it's not a bad interpretation
If a girl uses you as emotional tampon, there has to be a boundary even though if you had too much time listening to her problems

If you have expectations of trying to be her boyfriend or getting laid, you're bound to have disappoinment. A lot of times we execute plans without even thinking in future cause the quality of future moments depends on current quality of the action.
