Of all the things that might happen, much as we'd like it to be different, I can guarantee that this is one which won't happen.
However upsetting it may be now (or looking back in the future), time isn't going to wait for you and all those firsts, all those events and experiences you miss, won't wait and won't happen again.
We tell ourselves it isn't a choice but for many of us it is. Most of us could earn enough money to support our family comfortably in a relatively regular 9 - 5 job. We might not be personally as satisfied and we might not be as financially well off, but we can choose one possible version of our life over another.
It's absolutely fair to say that you have to balance the needs of being a "good" father (which let's remember is a subjective term in many ways), against your own personal needs (and indeed the needs of your partner, the rest of your family and so on), but most people reading this board are fortunate enough that there genuinely is an element of choice.
No-one should tell you that working long hours so your child need never go without (or so you're personally happy and the time you spend with them you do so without resentment) is better or worse than coaching their sports team and being there every bath time, but whatever you decide to do, I think the most important thing is to accept that you're doing it because you made a conscious decision - ultimately that's going to be the only way you'll be at peace with it.
And if you haven't made a conscious decision, the for heavens' sake sit down with your other half and do so. Of all the outcomes, doing what you're doing without thinking about what you want and what works best for your family maybe the only truly bad one.
