Regardless of how you build the ad out, no guy on Craigslist or any other dating app is looking for a long term relationship. They're looking for a sex hookup, money, kink, prey.
Women abandoned these sites long ago.
Most of the profiles of women you see are fake, to get men to spend their money on the site because the know men are desperate, or they are 3rd party catfish scams.
And look at how the "most normal" men behave on these sites. Wouldn't you run for the hills too? Anybody can say anything. It's very easy to type out that you're looking for a long term relationship. It's something else entirely to actually mean it.
Just saying.
