Long time lurker, posting to get some advice.

Been seeing a girl for a few months. We both said we're not sleeping with anyone else, but it's stayed pretty casual.

Things aren't really clicking, though, and she's failed to respond to my texts a couple times. I'm ready to break it off.

My question: do I do it over text? Call her? See her in person? None of the above, and just let it fade?

I'd like closure, but some friends say it's not even worth it, and just assume the end and move on.

Thoughts TRP?
