A Little Too Into Roleplay

I'm starting to wonder if I took my interest in DDLG a bit too far. It all began as an adult roleplay with my partner, where we would occasionally indulge in some playful age-play and strict discipline scenarios. At first, it was just light-hearted fun - he'd call me his little one or use the term 'daddy' to set the mood for our intimate moments. We both enjoyed it in small doses. But over time, I found myself craving more of that dynamic every day. My partner seemed game at first, but as my desire grew stronger, I noticed he started backing off. He's probably worried about crossing some line or making me feel uncomfortable. Yet the truth is, being reminded of rules and boundaries turns me on in a way I never expected. It feels like a secret world we share that others wouldn't understand. I haven't voiced my concerns - mostly because I'm not sure what exactly I want from this arrangement beyond what we've already explored together as consenting adults. The thrill is undeniable, but so is the risk of overstepping some invisible boundary between fun and something more serious or unhealthy. Right now, it feels like a delicate balance that could tip either way at any moment.
