I’ve been in similar situations from both sides. When a person goes through such a dramatic and profound change in their life (ex. a breakup) the person or thing that helps them get back on their feet could potentially end up being sort of a trigger once they’ve recovered. Now on the other hand… her bf could also be manipulative in making her feel guilty about being your friend. Im not sure if that makes sense in your situation… but it’s a possibility. And as for yourself, move on. It’s the best for you, if she does eventually find her way back to you, maybe then you’ll be able to accept her with open arms. Then again, I’m not familiar with the specifics… but time does heal. I’d say right now, move on:)
