Help me out with a few problems involving bud?

If you can't be attracted to someone when you're sober, you're not really attracted to them. Sooner or later, the smoke clears and you're dealing with the same person. You shouldn't have to be high, drunk, or otherwise impaired to want to be with someone. As for talking about other things, I suggest developing other interests and hanging out with new people. Not bashing your precious weed, just saying that if it's all you talk ever about, you really need to reevaluate a few things. Go do something else for a while, get a hobby, talk to people who don't smoke weed. You can still smoke it, but you'll find that you have more to talk about. It's not stopping, it's using it more moderately so that the habit you described doesn't interfere with you living your life.
