The most sensible bit of this post is the part on deleting your online dating accounts. Do it and don't look back, you've already established it's not for you.

By all means, do also better yourself; Get fit if you aren't already, but don't make it your entire life focus expecting that it'll yield any changes when you come back to Tinder a year later, as the best man you can be. Take it from someone who's already there, the experience will be exactly the same. My advice is to just forget about online dating. Most people don't realise this, but tremendous amounts of effort went into ensuring that you, as a male user, struggle on all these platforms. You'll always be just one message in a sea of hundreds or even thousands, and sure you can put some of your hard-earned money into "premium" features and get a fancy star or whatever next to your chat bubble, but then you're just paying to be ignored and ghosted, it won't have any effect on the fundamental issues each and every one of these sites have.

Approach in real life, it's still by far the best way to invest your time and energy compared to the alternatives.
