Help??

I haven't been on in a while, but my baby Marley is acting very clingy towards me lately. It's not towards my fiance now, she has become more of a Mama's girl, and strangely getting clingy. She won't leave me side, and she follows me everywhere. Its not like her. I don't know what is going on in her mind? Anyone have any ideas? Or have ever had this happen to them?
