Sometimes I think that I may not want a relationship anymore.
Wow! Do you regret your current relationship?
It seems I was being very naive getting into it
I'm sorry your relationship isn't working out for you, and you have all the right to break it off and be single. Why stay in a relationship that keeps making you unhappy?
Maybe. I'll wait and see how I feel in a couple of months.
You can always be single if that's what you want to be. There's nothing that says you need to be in any relationship at all.
