I've experienced something similar with a friend of mine. Ever since she owed me, she starting avoiding me like I'm the plague. Anytime I tried to talk to her about anything apart from the debt she thinks I'm indirectly asking for her to pay me back.
Money changes a lot in person relationships. Sometimes, even effective communication like I mentioned on the post doesn't solve the problem. Some people will just duck you and never come back up again.
Thanks for stopping by :)
It is crazy how some get controlled by money to the extent that they allow it t ruin relationships.
