Why do I run in too many catfishes?

You have to trust your instinct unless proven wrong. Just stay away from places that have a high percentage of scammers. 

Just pay the 30 monthly subscriptions on dating websites or either you stay in the environment where scammers, trannies run wild. 

It should only take you 1-3 months to find a match. 

Why do I keep running to fat girls? because I am always at McDonald's.

If you want to meet some decent-looking women, you go to the gym! go to bars & night clubs.
