I'm not quite sure how you're equating waiting around for a man to decide to marry and have kids with you with feminism.
As @Brefugee says, feminism has given us choices. What we do with them is up to us.
It is almost certainly the case that the number of women who would like to be happily married to a man and have his children is greater than the number of men who are willing to be a good husband and father. This means that a number of women are going to end up disappointed, whether they end up married with children but unhappy and unfulfilled, in a relationship with a man who strings them along for years but never commits, or single.
What is clear is that wasting your childbearing years hoping that a particular man is going to commit to you when he shows no signs of being willing to do so, is not a feminist choice.
In Jane Austen's time, if Mr Bingley or even Mr Wickham didn't ask for your hand in marriage within a reasonable timescale, you sucked it up and accepted Mr Collins, because it was better than ending up unmarried, destitute and dependent on the charity of others.
Today, we don't need to marry Mr Collins, there is no reason why being unmarried should leave us destitute, so if you choose to waste your 30s on Mr Bingley or Mr Wickham who is taking his sweet time and never intends to commit to you, that's on you.
