When he opens his mouth - is he saying things that will portray him in a certain light?
"I am a feminist"
"I believe in equality between men and women"
"I am kind"
"I am a nice guy"
"I am a good, hardworking, honest man"
"I love you and can't wait to be a loving husband and great father for our kids"
"I am not like the other guys"
"Not all men, I don't act like that"
The opposite kind of light counts too:
"I am not a good man"
"You deserve better than me"
"I am a bad influence to you"
"You are too good for me"
etc. etc.
The basic rule is this - if he can't help but talk about things that push you to think of him in a certain way? Like a politician keep saying to supporters that he is a "good honest man with family that works hard" - he has an agenda. And not a good one. Get up and leave.
OR he says the opposite - that you "deserve better than him"? That is him telling the truth about himself. Get up and leave.
A genuine HVM won't talk about things like that - if he tells a story involving him - he will highlight the funny situation, the peculiar anecdotes, the participants in the story. He will focus on the details of the story where he just happens to be a participant. Just like how your good friends will share a funny story with you.
But beware, while some scrotes will be very obvious in their portrayals - but a more seasoned manipulators will subtly insert his portrayals here and there after getting you hooked up to his stories.
If you notice that you start thinking of him in a certain way after a period of talking to him/calling him/texting him - and that is due to the things he say rather than you very own conclusion after observing him? You are falling for the portrayals. Get up and leave.
Stay safe ladies.
