Won't be easy given how long you've been a runner.
But you're now going from being a runner who's a husband/father to being a husband/father who is also a runner.
Work as hard at that primary role as you did all these years training and the success you'll achieve and enjoy will far outdo any successes you ever had in any race. And the running will fall into place.
Use this time with the remodel and ####ty weather to reset, maintain a base, then come back strong in the next 2-3 months when both of those things improve and then see where you end up.
You got this.
Seriously,
@gianmarcois right. (I hate saying that.)
Priorities adjust and change over time. When you are single, its easy to spend tons of time running 80 miles per week and drink beer with your buddies 4 nights a week.
However, marriage, house, work, kids, etc, all start to chip away at the time you have to run. You do a lot -- from going to a fair amount of sporting events to concerts, etc. I don't do much of that anymore (I used to have season tickets to Red Sox -- 12 rows behind home plate) and part of it is because I want to be able to train hard for my marathon. Plus, I generally enjoy being home more than out at a game or whatever. I prefer to spend my discretionary income on races and trips.
I hate to say it - you (and I, as well as many of us) are at the stage where PRs are going to become more difficult. If you keep searching for an arbitrary time goal, you will become more and more disappointed as you age.
Find the joy in your exercise routine. It could be winning your AG in a few local races, or improving your age graded % results, or losing that extra 5 lbs, or beating me on a Peloton workout

, etc.) Whatever it is, make it something that brings you joy as well as is good for your body.
For me, I enjoy the journey of seeing what my body can handle during a training block. The emphasis on one singular race is almost secondary to the journey to get to the start line fit and ready to rock and roll. I also dove headfirst into pacing as I knew my competitive side would eat me alive as I got slower as I aged. Pacing enables me to be the best damn pacer alive....even if its eventually leading the 5 hour marathon group when I'm 70.
