Definitely something to think about:
"If you feel like you’re being used, you’re very likely being used – friendship or a relationship feels and looks like friendship or a relationship. Using, looks and feels like using.
If you haven’t twigged that you’re being used but you’re subsisting on a crumb diet while they feast on the fringe benefits and then some, yeah, you’re being used.
If they’ve aligned themselves around you at a time when it suited their greater purpose of having a place to stay / money / a job / a reference or just seizing on a vulnerability that would have you giving to a greater degree than you would under ordinary circumstances, you’ve been used, especially if now that you no longer serve a purpose or have figured out what is going on, they’ve suddenly disappeared or have become quite mean towards you.
Once you suspect or know that you’re being taken for a ride, it’s stop, look, listen and step back and adjust your boundaries time."
