What's after Fubu?

I had this fubu for almost roughly 18 months din. I became very attached to her kahit yung small life decisions nandon sya. But when we ended it's been hard to move on from her or more like naghahanap ako ng what we had sa iba but i figured na mahirap pala.

So just wanna ask on what do you usually do after having that fubu or fwb na sobrang solid how do we detach?
