So much.
Through the whole process, I was really able to get in touch with my emotional side, better understand it, cultivate it and most importantly grew it into maturity. It's so liberating to be able to understand my emotions (from someone that had a very underdeveloped emotional side) and recognize them for what they are.
It's a long road, but well worth it.
Along the same lines, I say sometimes in a joking manner that before I met my BPDex I didn't know I had emotions. But it is kind of true. I am a sucker for the feeling of love, and once I finally felt it for the first time I was hooked. Losing it was awful... .so yes, I became much more emotional after the split. Crying my eyes out, feeling depressed, etc.
