I wouldn't blame this on bpd, not just yet anyway.

Of course its fizzling out if you're at the "same ole same ole" stage...

Nothing new or exciting is happening, its expected.

My bf went abroad for work, we make it a point NOT to talk / text ever day... Otherwise we'd run out of things to say and also fall into the "same ole same ole" trap.

There's only so many words in the dictionary you can say to each other, and if you're saying them daily, the well runs dry, it's the natural order of things.
