She always says I am a huge catch, and contrary to her previous relationships, says she wants and chooses to spend time with me rather than feel like she needs to. There are many more "green flags", but I think you get the idea.

The thing is, she has slowly stopped hanging out with her girlfriends and coworkers, and only wants to spend time with me. I am afraid I am letting her become clingy and this can be an issue in the future.

She often brings the fact that she wants to take care of me and she agrees with the captain/first-mate dynamic.

Am I being a jackass and not seeing that I have a unicorn in hands, or am I right to be thinking this can be an issue?

I just need some enlightenment. Thanks everyone in advance.
