I will say ... like the little cynical woman I am, some women will have virtual relations with a guy to keep him on the hook and to keep him being her well.. "emotional support" that she needs. (see and this is where some guys get confused, they think well.. I was her emotional support just as friends, for a lot of people that support is better entwined with desire, like an ego stroke).
My bestie at the moment is doing this to a guy in real life, her relationship is so abusive and when she goes to the gym she offloads onto a guy, he emotionally supports her and she throws him a bone... for his.. service? Not full on cheating..but.. inappropriate behaviour like flirting and blah blah.
But like many have said we just don't know enough to draw conclusions or make judgements so I am deffo not doing that, I will say, if you find that she is actually amazing and it was her relationship previously holding her back then.. I'd say goooo for it life's too short not to right?
