Sometimes, no matter how hard we try, no matter how much we love our friend, things just do not work out. Maybe it is not about you at all but about the other friend. Here are some of telltale signs that you need to be careful about:- .Your friend criticizes and insults you in front of others. .Your friend tries to isolate you from the rest of your friends by bad mouthing them. .Your friend ignores you and then apologizes: it is an endless cycle. .Your friend forcefully tries to set you up with someone else.
