The problem is the sense of entitlement from attention women receive nowadays from OLD and social media. Women's attitude towards men have shifted dramatically the last decade or so. It's getting harder (in my experience) to raise or maintain their interest level with so many options.
A guy's game has to be rock solid to maintain frame and she has to know the guy has options to stay interested. If he doesn't or senses that he doesn't, she's likely to lose interest fast without competition and look for the next challenge or circle back to an orbiter or ex.
The ability to pair bond with a new partner and form a lasting LTR is harder after having loads up hook ups, abusive relationships and divorces once they start navigating their 30s, heart matters become complicated. Relationships don't start and flow easily. There's more resistance. More interpersonal reservations.
Guys aren't approaching women in massive quantities IRL. Yet... online the flood gates open when they make an OLD or social media account with selfies, etc. Too many thirsty dudes out there sliding into their DMs hoping for a date or hook up.
I d/l coffee meets bagel last week. I found a good match and hit the like button. Do you know what happened next? I got a prompt on the app saying there are 50 guys in front of me waiting for her response, yet if I spent my earned bean "currency" or pay for a premium; I can move up the line. WTF? No!
I imagine without the proper lighting, angles, new photos the attention will go down at some point post-wall.
What most of the women struggle with is weeding out the desperate AFCs for their top pick(s). They ghost, radio silence, ignore or block the ones they aren't interested in dating. Nice guys (w/o game) don't get them excited are glanced over.
Not every nice guy like the author says becomes super successful in his 30s. He probably worked hard on his LMS to raise his SMV, yet is hurting to stay afloat and forge ahead. What is hurting him though is his attitude of becoming cynical from compound rejection.
I will end by saying it would serve him well to create a fun life, have great social spheres, hobbies, and strong family relationships. She can tag along. If he's smart, he'll continue to screen the ones with high mileage, AW, professional daters, and other toxic types.
