My Secret Guilt and Shame

I’ve always been a proud military spouse, dedicated to my family. Recently though, I started this strange DDLG dynamic with another married man. It’s not like we’re cheating or anything; it's more of an emotional connection and roleplay. But every time we meet up, there’s this intense feeling that overwhelms me, I don’t know how else to describe it but it feels almost forbidden, even though everything is consensual. He calls me 'Mommy' and treats me as if I’m someone who can take care of him in a way that has nothing to do with our usual duties or roles in life. I feel so confused because, on one hand, it’s thrilling; but then there's this nagging voice in my head telling me something is very wrong. Am I just being old-fashioned? Is this okay for people who have families and commitments outside of these sessions? Please help me understand if what I'm feeling is normal or if I should walk away.
