This is a point far more general than coding. As we grow, some of our tastes change, and that's fine. "I will always feel this way about X" deserves to be labelled as some sort of common logical fallacy if it isn't already.
12 years ago I moved away from a pure coding job because it lacked other things I was seeking. Nowadays (as a 38yo academic researcher) I don't get enough of it so I code a bit outside of work to keep me motivated, but I'm seriously considering moving back to a coding job despite many other upsides to what I currently do. Having done some networking in that job market I don't see that being a problem, should I choose to go that way.
Maybe if you stop altogether you'll end up missing it like I do, maybe you won't - doesn't matter - go with what you want to do. Like Spolsky says there are great rewards out there for developers who fully understand software but can work effectively with people who don't.
I am scared I will be asked a lot about why I am switching back into coding and why I left it in the first place? I am scared of coming across as indecisive
"I was given an opportunity to lead a product I was very excited about, and I took it. It was a great experience, and I learned a lot, but ultimately now I'm glad to be moving back into a developer role."
If you can truthfully say that, you're conveying not indecision, but rather showing the flow of your career path. That is something that is expected to take a few twists like this, and that's even a sign that you're someone with flexibility and a variety of skills, as opposed to being inflexible and unwilling to do things that are "outside the box".
My previous company saw project management as a step up, whereas I see it as just another role. Many engineers make poor project leads, and many project leads make poor engineers. Unfortunately, our society values "people" jobs like leadership positions more than technical jobs, so people will see it as a downgrade (especially those in management).
Ignore that noise and do the thing you like that helps you meet your other goals (financial, lifestyle, etc).
If you switch roles and after a couple of years switch back again - no problem!
If you start to have a history of every six months to a year switching roles or moving companies, that can start to look bad, yes. But even that isn't a disaster that can't be overcome.
I wouldn't worry about it.
As a bonus, they tend to have more empathy for what i have to deal with, so when they ask for support or process changes their ideas tend to be practical and reasonable.
Unlike the top comment, I don't think this has to be a sign of burning out (although it can be) - humans are complex beings. The world changes, and we change as well. What was enjoyable to you 15 years ago may not be as enjoyable now, and what you enjoy now might not be what you will do for the rest of your life. At the same time, if you find that you miss coding, you can always return to it later.
If life pulls you towards a more customer-facing role and you discover that you like it, that's a best case scenario to me! Go for it.
I've been coding since childhood and I'm 38 now - and I have had periods where I did other things and enjoyed that as much if not more than coding. Rediscovering a passion is a great experience in itself, worth having at least once.
