Your boundaries are your limits, self-love, self-care, and self-respect. If someone doesn't respect your boundaries, they don't respect you, so give them less access, distance yourself from them, minimize your interactions with them, and most importantly, stop respecting them.
Adulting Advice??? Travel once a month or every other month this year. Road trips, quick 1-3 day trips or whatever. Just get away and create memories, experience something different. Solo, couple, with friends and family trips are all needed to balance peace and adventure.
