In my opinion, if a person is loud about something, that is what they are most insecure about. I remember when I was in a not so good relationship. I constantly reminded everybody how so in love I was or how good we were by daily social media post, but that was furthest from the truth most of the time. There’s a thin line between insecurity and actually being proud of something. Nothing shows just how secure and at peace you are about something more than the ability to not have to show you are just that. When you actually have it, you don’t feel the need to be loud about it.
