Not sure if I qualify as an "Older Guy", I'm 27 and recently married. She understood my crazy work schedules back when we first started dating. Even once we got married we actually only got about two nights a week home together. Her schedule is more hectic that mine lol (She's supervisor in a home health service that tends to non-elderly with physical/mental handicaps that live outside of group homes)
Before I even began the application process for Medic school, I explained everything to her.....How much I wanted to do this, How much my student loan will be, How I'll be spending a butt-load in gas driving to/from a school that is an hour one-way, How long the program is, and how I'll have to do ~700hours of clinicals and once those begin I would have to cut back on my shifts and use that time for clinicals so it might not make a huge difference in "Our" time but we might feel the punch in the wallet.
I'm in the clinical phase now and it really isnt interfering much with spending time together. I'm not falling behind in clinical hours, and I'm actually not having a problem getting my required contacts/procedures. We are feeling it a bit in the bank account but she's working a little extra when she can for some extra cash.
Come spring when I'm done, we will switch places. I will work a little extra while she cuts back so she can go to nursing school
