Been there, done that, run a mile.
Also, no judgement here from my part but just noting you seem to value a potential partner by external status factors just like you say your player guy does - I quote:
'It's happened to me. I had a long term relationship when I was much younger with a man who first time I met him, I just wasnt interested. A year or so later, hed changed - had a lot of career success, more confident, put more effort into his appearance - so he went from being someone who wasnt my type/didnt attract me to someone who was.'
and about the player you write:
I maybe wrong but I get a sense that money and status are important to him'
My advice would be to focus mainly on internal qualities and a dynamic between you and another person, whether it's a male friend or potential partner.
My beloved DP was 'just a friend' for me for quite a while before by luck I started to see him in a different light, and fell for him - we were already close friends by then so it's all been great from then on, now we live together etc. He'd always expressed interest in being with me but I'd said it wouldn't work out for more than a few months and our friendship was more important. I'm so glad to have been completely wrong.
Quite ashamed to admit but I do remember I didn't perhaps consider DP quite my intellectual equal when we were just friends. But I was wrong, he is a mild-mannered person and very smart and interesting, just not a show-off who shoves it in people's faces, hence took me a while to notice.
As for status, he works for a minimum wage but I could not care less about that. The genuine love and passion we share is worth more than any money in the world.
But it is easy to get blinded by all the different views and ideas in the world today. I'm actually happy to not have a partner who's pursued by every woman in town as it would just be fishy and probably cause an average guy a big head. I guess I've always been for the underdog.
It doesn't have to be a choice between the 'popular guy' and an underdog who's not 'worthy' of you. Unlike a certain presidential candidate, I don't think either women or men can be rated on a scale of 1 to 10. There are about a gazillion factors at play when determining partner suitability, which is of course always a dynamic, not an individual value, if that makes sense.
Ironically the initial reason me and DP were just friends for quite a while before getting together was that when we met, I was in an on-again off again relationship with a guy who believed in polyamory. I was very much in love with him, or so I thought, but when he did the shit on me for the 4th time, I walked away and felt free. He of course kept pursuing me for a bit afterwards. These men only want you when you do not want them and it is toxic, disturbing and something to steer clear from.
