Go on a few ridealongs, to get a feel for what the job really feels like. You've got some good experience with one of our common demographic clients, but there are others.
You really have to need to be in this line of work, not want to but need to.
Because the novelty of being the cops will fade, it will separate you from your non-cop friends, the nights and weekends, missing holidays and birthdays, sporting events and dance recitals will wear on you and your family. You'll probably get sued, hopefully quietly. But you could end up the hot topic of the day on MSNBC too, getting your ass doxxed off. And that's all still possible if you do everything right.
Getting into the profession after you're married will strain your marriage because you will change. It's just a fact. You will miss "get togethers" and afternoon BBQs with other couple-friends and thier kids, or holiday parties with friends and family. It's going to be up to you and your wife to figure out if your relationship is strong enough to weather that, and you won't know for sure until you're ass-deep in the problem.
This job will change everything about you: your personality, your social life, your sleep schedule, your health, your emotional life, your marriage. That's not a "good" or "bad" thing. It's just a fact. Up to you on whether they're good or bad changes. (spoiler alert: it will be some of both.)
I'm painting a bleak picture here, because it can be very bleak. This job can absolutely chew dudes up and spit them out the other side: physically broken, emotionally destroyed, divorced, and bitter. It's not just a possibility, but for some, a probability.
The job can be fun, I absolutely love my current assignment because I hunt no-shit bad guys now, instead of chasing radio calls. But if I got pushed back to patrol tomorrow, I'd still be doing this job because this is where I belong and I need to be doing this. It's a profession for me, not a job. I'm on year 14 too, so I've been at this a minute. Long enough to watch guys flame out who liked "the idea of being the cops" , way more than the "actuality of being the cops" and all that comes with that.
There's a lot of risks and downsides to this profession for you and your family. Only you can know if you "have the song" inside you or not. If you do, good on you, because we need good dudes, who are in it for the right reasons.
