I don't think it's your insecurities, I think it's just how it is now. She actually sounds a little insecure with that Uno game! Is this a new relationship for her? I don't think you sound clingy at all and if you want to talk to her, there's nothing wrong with that. Some people just don't seem to be good at keeping boyfriends and best friends at the same time. I have definitely done it myself, wanted to spend every minute with a new boyfriend, and I've lost some friends that way.
