More power to you. I agree, you can meet some wonderful people on apps. It's not that I'm against, just that, from my perspective, they've stripped dating of romance and effort, and to me, that seems sad. Now, one can flirt with a potential partner while on the toilet, and that's a wee bit nasty to me.
I don't really see the harm.
There isn't one, as long as everyone's content. The harm only appears if either they tried to change your lifestyle, or you tried to change theirs to suit your own. Other than that, to each his own happiness. It's excellent that you've found something important and valuable, and a system of prioritizing the things in your life. Many don't.
Commitment, I believe, will be spontaneous when I encounter someone who shares similar values and we also have a physical attraction that pulls us to that kind of union.
I think you're right, and hope you find that :)
Thanks, you as well if you desire it :)
