Is it best to not date or see other people when you know your long time friend likes/is in love with you?

This may be unpopular and people may disagree and that’s fine. Just hear me out. If you know or knew that your long time friend likes you or in love with you or just finding out they are hot for you, DO NOT DATE OTHER MEN OR WOMEN! You’re just leading them on and keep breaking their hearts! If you’re meeting someone knowing that your guy friend or female friend likes you or in LOVE, then you’re going to break their hearts! Don’t chase or date other people if you I know it because to put it bluntly, you’re a selfish jerk! Give them a chance! If you like them back.

I have a friend that keeps thinking about her guy friend and she can’t get him out of her head. I told her, “I hate to tell you this but…. it sounds like you’re having feelings for him! And you said it will NEVER happen. Plus he’s really improving himself. You don’t find that attractive? Plus he’s being more approachable of impressing you.” She’s worried about how he would feel if she ends up meeting someone else and hurting him.” I told her she should think about what she wants.
