Nah, you aren't a silly girl, you are human.
I had sort of a similar thing occur, and I even spoke to my T about what was happening, he said it happens often, during a time of someone's life where they are in crisis or just in need of someone to listen, the client/patient get to feeling "someone cares", and starts to have close feelings. It can even reach points where one starts to fantasize . . .
My former T called it infatuation, and ruled out transference, but even that may have been questionable.
Due to job relo, we had to move so the T became "former", but even if we hadn't moved it was becoming uncomfortable for him and hurtful to me, cause he sort of became nasty with remarks of the time he "invested" in working with me, etc. hell, I paid for my sessions, so I even became confused, "was he even starting to like me"? I'll never know, he barely said "good luck with our move," at our last session, which he just had me sign a release for his record of me to be forwarded to the new pdoc and T, where we had been relocated to.
What you are feeling is not unusual, but try not to allow yourself to get caught up in this, it can be an obsession that hurts in the end, especially when you come to realize or are told that the feelings aren't mutual.
Please take care,

I'm wishing you lots of healing and luck with this.
