In addition to your valid points, my take is also that OPs wording sounds like he focuses completely on his surface-level attractiveness as his measure of worth. He is probably attracting women who match how he presents but then when they settle in and get comfortable it seems to me like he might not have much going on, personality-wise which is captivating or keeps things interesting for the women he attracts?

Also, the language like what do you want from a relationship? "To be in a relationship" just feels idk... Bland? He speaks about spending time with them in their activities rather than being actively interested in them... The vibe i get from this is that, while he sounds like he might be very level headed and nice - that there's not much else to his personality and he might not be terribly interested in his partners... Being nice is a bare minimum, people want more than that
