That's sort of "funny" for me to write since that's the original reason she gave to me on BD for why she said "she hasn't been attracted to me in years" - i.e. I wasn't able to provide the emotional connection she needed to be attracted to me, and she didn't think I was capable of it.
Believe her! This is what all these situations are about. The rest is all how deep you want to go. If you want to get hung up in the MLC world you will get stuck for years. She lost attraction for you from probably the 1000 little things you did over the years. So you can A. Learn from it (read books on what women are attracted to), self improvement, etc. and move on or B. be stuck in forever limbo hoping she has a change of heart. The choice is yours and you only live once so choose carefully.
