You can still break out of friendzone if you were not decently charismatic in the past. Whether it is post or pre divorce life it doesn't matter much as long as the girl can rationalize being with you

you want to cultivate a firm mindset and right sets of actions when interacting with women

they don't want a wishy washy guy
If you like her more than a friend, try to ask her back to your or her own place. The romantic or sexual interest is already clear

It's fine to have some close girl friends cause they will introduce you to her other female friends also

If you don't count in time and money putting onto maintaining a relationship with a female, it can be a great experience

you make the move to see whether she's just friendship or something more. It's just this simple

Don't need to overthink
