Why would a girl say she's about to be single and say it was about family when I asked her what she meant?

A girl I've been dating said in her Snapchat story she was about to single and she is living the single life. When I asked her about it she said it was about family which was odd. We haven't been speaking for a while since it's long distance. Part of me feels like it is dissolving and it also isn't working.
