Should I marry them after only a few months? Or am I too obsessed with my partner?
That depends. Do you think that you are moving too quickly into love?
But I am so in love.
I get how easy it is to move fast in a new relationship. You should not get married after such a short time though. Take your time to get to know the person.
It's fine, we know each other well by now and everyone else should mind their own business.
You cannot know each other that well after only a few months. You should wait a little longer to make sure you are compatible.
