many would argue an experience happier than the one being lived by someone who is not out. However, because you are not out, you are happy but know no different and so you can't truly gage your happiness vis-a-vis being out. Only those who are out can truly say they are happier than if they were not or that they were happier when they weren't out because they have experienced both states. Your current state of happiness is only relative to what you know, and as you don't know how much happier/unhappier you would be if you were out, to say you are happy in a definitive sense is somewhat self-misleading.
I am not intended to compare my happiness with someone else's happiness. I am not either intended to say I am happier than people who come out. ^-^. Live with your choice and be happy. Come out if you think it is worth it. Every choice have consequences. No matter what it is, you can be happy if you can deal with those consequences. No gauge for sure. but, for me, happiness will arise when I love myself, respect myself as I am. No gauge but I can feel it. And I hope You are happy, no matter your choice is. No need to compare, I guess.
