Her idea of cuddling is spooning, making out the entire time and constant hugging. It's cool I guess but yesterday I was receiving from a night out with my friends and only slept 5 hours before a bartending shift then I had a online final. I was dozing off cause my redbull wore off and I crashed. So i started to pass out on her shoulder/breast area and she told me I better not fall asleep and kept tickling and kissing me to keep me from sleeping. I didn't want to call her out so I went with it but I was pissed.
What's weird is that you can't be upfront to her and tell her that you really need to sleep. If she's a good girlfriend, she'll understand and leave you alone. Also it wouldn't hurt to tell her that you need some space every once in a while. You should be honest about your thoughts. Not brutally hones though, there's always a nice and respectful way to express yourself.
It's not weird at all. My boyfriend also think I like to cuddle too much. Though, there is a difference between wanting it a little too much and pissing you off because of it. I want to cuddle too much with my boyfriend but I also know not to bother him if he's tired.
