Something strange lately with this girl that i've been dating for 2 months?

Recursion
I've been dating this girl for like 2 months +(and in total know her for like 6 months), now we had awesome dates and she even used to tell me that she's having so much fun, really we had awesome time till the last date that was bad cause she saw her ex and the date went bad, now after that date I've noticed that she acts weird and everytime I try to plan a date with her she doesn't show any interest in dating, we still do speak on phone everyday and we talk but I don't know what to do.. should I ask her if she still wants to date with me and keep this things? I mean I dont really know what happend :\ and now we didn't date for like 2 weeks.. we used to date every weekened
