Engagement

My SO and I have been together for 10 years. He was previously married so marriage again isn't very important to him. It honestly wasn't to me either but in the past year or so my feelings on marriage have changed and I'm realizing I don't want to be "single" for ever. I want to be a wife. I spoke to my SO about my feelings and he said we could get married. He got me a ring but just like gave it to me... He didn't propose or anything. I find myself having trouble saying we are engaged because it didn't really feel serious. Now I'm not expecting some romantic crazy proposal, that's not really my style but it would of been nice if he at least asked when he gave it to me. Am I being a brat?!? Honestly if I am I want to know.
