To think this behaviour isn’t normal?

[sharksortigers133]

Male friend bumped into someone he vaguely knew (family friends son) and this man then added him to all social media and started flirting.

Unfortunately it became quite clear this man was in the closet and has a girlfriend. He made a lot of false promises to friend but nothing happened ... they never even saw each other other then that one time they randomly bumped into each other.

Months later and friend is still obsessed, talks about him constantly. I went out with him last night and he drove me home the very long way .... he then said he was going to show me this mans house and he said when he’s in a sassy mood he puts his music on in his car and drives past his house sometimes.

Is this normal? Do I need to sit friend down and tell him to stop it?

Does sound odd that he's talking about him etc . Yes maybe have a word but if he's admiring him from afar that's fine but anymore then definitely have a word .
It may be a little like people get obsessed with celebrities, would never do anything but I imagine they are in love with them . It may be harmless but he needs to be careful it doesn't cross into stalking.

Is Stalky a good friend of yours, and inclined to take advice from you?> If so, it might be a good idea to suggest he puts some effort into his social life whether via groups or onine dating: this man has probably forgotten all about him by now and being obsessive about someone who isn't interested is not healthy.
