I'm currently halfway through a period where I miss a lot of life as I'm studying while working full time. My time commitments make it very difficult for me to do many activities, I'm often too tired anyway and I really cannot commit to a serious partner for another 2 years despite the fact I prefer to be in a relationship. I occasionally have periods where I feel like life is slipping me by but I refocus and remind myself that this is only temporary and that I'm working so hard for my future with concrete short-term goals.
On the other hand, I'm quite lucky. I have two children who I have more days than not, so I don't have the fertility pressure the author of this article has. I suspect her biggest issue with her life is her fertility, as she sees an entire path her life could have taken fading away rapidly. I've dated a lot of women over the last few years and the one thing I've noticed is that women over 30, and especially 32, often seem more focused on finding a father for their children than a partner. The author even touches on how hard this makes dating, the pressure these women feel to get serious and start a family in a very short period of time.
I'm 33 now and I have a large number of female friends who are reaching the point where things are becoming urgent. They've had these amazing lives so far, full of travel and hitting career goals, but they've neglected to find a stable relationship and now they're looking at their own fertility. I recently attended a small reunion of some college friends and of the 4 women, only 1 had children while 2 are 33+, single and childless and both of them seemed to want a partner/family. These are great women too who would have a lot to offer in a relationship but it's just hasn't worked out that way.
In either 12 or 24 months, my ex-wife and I are moving to another city nearby where her family is. It's smaller, cheaper (I could buy a house immediately), has a really amazing beach culture, etc. I intend to plant roots hard and put in a lot of effort to meet new people and make solid friends
