I can't sleep. I've been thinking about Rhea Ripley all night.
Why are you thinking about her so much?
She's the girl I kiss and touch...the girl who is next to me as I type this.
It's not healthy to obsess about celebrities, especially when it sounds like you are already in an intimate relationship.  It is disrespectful to your girlfriend to pretend that she is somebody else.  You should love others for who they are, not who you want them to be.
I can like whoever I want.
You can like the celebrity, but it should not impact your life or your relationships. That is when it goes too far.
