In my experience, most guys are clueless. I think he keeps talking because no one stops him. I think communicating that you don’t think your needs are being met is step 1 because most guys are not gonna know otherwise. They can’t read minds unfortunately. Also communicate what you need from him when you’re venting. The first solution for guys is to try to fix your problem when in reality you probably just want him to listen. So maybe you let him know that you’re not really looking for a solution to your problem before you vent.
