This girl, at times, made me feel so incredible. It wasn't only the sex. It was the extreme bond she and I had. I felt an intensity of love that I never had for anyone. I literally lost myself in her.
... .
Do I need to let go of all the good feelings she made me feel in order to get over the bad things she made me feel?
Same here. I loved her with all my being. But there's a catch. That, my friend, does not meet the definition of love. What did you or I get back? On my end, it was spiritual. On her end, it was clearly physical as she said she doesn't even know what she feels. That was the only complete truth that ever left her lips.
I chose to disregard the (frankly not too many) good things and break it off. Everything else, for me, would result in further entanglement in her web of lies, manipulation and, worst of all, lack of love and respect for me.
What is true in your case?
