I Take For Granted That You're Always There, I Take For Granted That You Just Don't Care

This song has been stuck in my head for days now. I don't remember the first time I heard it but I know that it's one of my favorites. I'm not even 100% sure what it's about (kinda sounds like an affair though), but I still love it. It's always reminded me of those times when you're kind of on and off with an ex that really meant something to you. It's a down low kind of thing but the lines can get so blurred that you start caring in ways you shouldn't and expecting things that you shouldn't. Just the whole vibe of the song is total 70's.
