I've noticed something in me that is putting unnecessary, painful obstacles between my partner and I, and I want to figure out what it is.

To illustrate: If a platonic friend likes something that I dislike, like heavy metal or baseball (just an example,) or thinks one way on some philosophical topic and I another, I can just be like "ah whaaaat" and move on and it doesn't bug me.

But if my partner and I disagree on the same thing, it hurts. It worries me. It upsets me. As if it's an indication that we're not perfect for eachother, or something?

I know its rather specific, but has anybody experienced this? Any ideas what's happening?
