5. They talk behind your back.
You may notice that your other friends have been treating you differently or that they seem to know all the drama
in your life without you even telling them. If you get the feeling they’ve been saying unfavorable things about you when you’re not around, it might be because they are.
6. They always forget to pay you back.
If someone is constantly borrowing from you but never giving you the money back, is it actually borrowing? While there’s a chance they may be forgetful, there’s also a chance they’re taking advantage of you and your goodwill.
