You (from the outside looking in on all this) ramped up the social aspect of the hobby, you def appeared to ramp up your chip sets or level of them, you've dove into the custom side and the relabel side, and you've moved into hosting your own meetup. At that point your kinda......done?
Just looking around, it happens somewhat frequently here. Would seem weird to let chip sets go though, just because of a lull. Something I've found helpful is the whole friends & family fror thing. If the money isn't super important but the chips were meaningful at one point or "grail" worthy, chances are they'll be meaningful again. Personally I'm all for moving chipsets, because someone else would be head over heels for some of those sets. It can be satisfying to see them in the hands of those that love them and will get them in play. You can get them out for reasonable price to trusted folks, knowing that they may end up back home with you one day.
But like everyone will say, there's an ebb and a flow. Personally my "boredom" of chipping came down simply to time, finances, and value. I don't have time to be full in on this type of hobby, it's out of my financial range as I'd rather spend on hosting a meetup or such, and with work and family the value add simply isn't there. But I would imagine most of those things will evolve or change for me, much like your situation is likely to change or evolve for you.
Honestly not logging in every day and keeping up is nice. And makes the times where you come back in to see highlights or catch up nice as well. Start there and see where the wind takes you!
