So we are bowling and I hate bowling and I had a bad time, but she said she had a good time and I told her I didn't.
Man, if you really try, if there is at least one person enjoying some activity, you can get on board with that and have fun with it to. Don't be a stick in the mud, think about who you're with, not what you're doing. You can have fun. She was having fun - you could have used that.
Not only that but you actually TOLD her you didn't have fun - why did you do that?
After that she probably started second guessing things and looking for reasons to not see you - and while the mistake you made is probably not an instant fail, it may have snowballed. You mentioned something about her saying you didn't have fun. I'm suspicious the bowling night made her second guess her opinion of you and then she just started to find excuses - such as you only want sex.
Instead of rolling with it and making the best of a situation (which can often produce unexpected fun times) you went in with the mindset for total failure, by being convinced that there's no way that night out could possibly be fun.
Worst case, even if you're not having a hugely great time but she can see you're making the effort, she'll respect that, and she'll want to do something else that you enjoy more later.
