I'm might be reading too much into it, but that's the vibe I got. She took an 80-week break from posting pictures while they were together, and then a month ago she started posting again. She posts a lot of vague stories on IG, including saying she's only going to date girls from now on. Even as late as November she was vague/sad posting on twitter. Also, they appear to no longer follow each other on Twitter.

Again, this is all just my assumption, but I figured that /could/ be a reason for delays.
