I'm sorry I asked for help here. You guys don't seem to understand that there is such a thing as a person who second-guesses themselves at every major life decision no matter how clear or right it is. My brother is the same.
We think too much to believe that just because we've found one person who is perfect for us that there aren't several others out there and we become curious what they're like, etc. Call it overthinking, call it what you will, but it doesn't mean that I shouldn't marry this girl.
If I were to choose to choose that, I would be making that choice completely and authentically, and in that moment deciding that this is who I want, regardless of who else is out there. But that's the hurdle, that's the leap of faith to make.. but once it's made, it's done and you've made your choice and you're in it for the long haul and there are no regrets because you chose it.
Anyways, now I'm lecturing myself. Have a nice day all!
You don't seem to understand that the internet is not a substitute for therapy. Or a place to ask for relationship advice. Or a place to pour your heart out.
