Sharing Our Innermost Thoughts

I have a friend who calls me up every time she is having issues with her I don’t-like-him-but-he-is-a-good-friend-and-affects-me-alot and I get it she just wants to vent and let it all out . But every time she calls , she keeps on talking for hours , literally HOURS. And I’m there going “hmm” “okay” “yeah” , dude take the hint , I’m not interested ! Stop wasting my time if you don’t even “like him”
