I'm going to call my girlfriend a stalker
That seems a bit extreme. Why do you think she is stalking you?
She gets jealous of my time
You shouldn't call your partner bad names. If she is doing something you don't like then bring up the reason why.
No.
While your girlfriend's jealousy is annoying, you should discuss the issue with her rather than call her bad names. Doing so is hurtful and won't improve the situation. Being more mindful of each other's feelings and boundaries seems like the more ideal solution.
