I think it's pretty normal. I went thru that with my first husband. I didn't love the man but we did part as "friends". I wa so happy with him not in my life. Wasn't attracted to him. Strangely right at the end when all was said and done we had a week fling (kinda strange to call it a fling when your still married) but it was just that. I knew in my heart that splitting up was the best thing to do and I guess it was just a need to say goodbye somehow. It is rather confusing!!
Hang in there sweetie. When I read your posts I can relate to your confusion. It's a reflection of my thoughts and feeling.
