Yeah she does. She doesn't seem to care about what other people/ her ex's feel.
Kirsty had a very busy love life, I remember her being with Seb and Kane but I forgot about Nick.
It's wierd how the scriptwriters are modelling Maddy, Ric, Belle, Lucas and Cassie on Seb and Co. Like the swapping partners in relationships and Cassie getting together with the bad guy.
