3. You speak fondly of some other guy.
“I only recently got over the fact that she’s not interested in me, but now she goes on and on about my friend…” a young man in his late teens sighed. “I get depressed just thinking about it.” It’s utterly insensitive of you to talk about someone you like in front of him, especially if you know how he feels about you. You need to be considerate by showing some interest in his latest romantic interests. Ask him, “Have you found someone you like?” and you may be able to offer him some support.
