Am I just supposed to bridge relationship gaps for women?

Like you’re not actually meant to date but you serve purpose to the girl until she finds her real relationship. I ask based on two situations the first being in 2017 I really liked a girl she told me she wouldn’t date me if I was the last guy on earth and actually had me give her number to a another guy fast forward to today they are happily married. I was in a relationship in 2020 she never really seem interested but constantly liked the attention I gave her, so she decided to break up last year fast forward to now she’s also happily in another relationship. Are some guys not supposed to have their own relationship and just bridge gaps
