Is it wrong to only invest in relationships you personally get something out of?

After all, we have certain time constraints on our lives. It is physically impossible for me to pursue genuinely deep relationships with all those around me.

So, if I'm being honest, I'm looking for your permission to bail out of those relationships with people I dread but guiltily maintain, and instead, focus on building the ones where I inherently enjoy the other person?

Fully aware you probably won't let me off the hook...
