Are you sure it is ONLY for that one reason that she still loves him?
Thinking back on all of the partners and lovers I have loved deeply in my life, save the ones that were just utter jerks, I still love ALL of them in one way or another, and I certainly always will treat them as family and friends. For the most part, when you do deeply love someone, even when a relationship changes, most people do still love that person.
But that doesn't mean they cannot also love someone else, OR that the next person has to "outdo" the last relationship. You don't have to do that, and you don't even need to try. I'm of the mind that in general, all our past and current relationships are all different (hopefully): they don't have to complete with one another. We have enough special places in our hearts for all of them.
I think in your case recognizing that is the biggest deal. The fact that he was the person she first had intercourse with is really smaller than it seems: bear in mind that as you grow older, you'll be hard-pressed to find women to date/partner with/marry/cohabote with, etc. that have NOT had at least one or two previous partners. Again, it's not a competition.
Who is she seeing right now? You.
