I don't know, either, but sometimes, when there is a crisis, we may cling to the 'safe' people we knew when we were younger, so that we can block out the worries of the present.
You say that she is getting together with relatives and old girlfriends, which would fit.
You worry that there might be an old boyfriend in the picture ~ but you don't know.
You are right, though, that this is a very young and vulnerable girl, who may not do things the way you want her to.
She is quite a bit younger than you are.
Maybe you should move on ~ or maybe you should be patient and give this relationship every chance.
Without knowing what is going through her mind, it is impossible for me to be sure what to advise.
But one thought ~ if you were 'the one', I would have thought that it would be you who she might want to cling to in times of crisis. That's how it usually works. But there may be a good reason why she isn't doing this, I suppose.
