I'm not a Christian, much less a Catholic, but I do believe that there's something to the idea that any sin can be forgiven with enough love, but only if you're willing to confess it and ask for absolution, y'know? Just my POV.
Me, 30ish bi female, been doing solo poly for roughly 5 years. Gia, Clay, and Pike, my partners. Davis, ex/friend/"it's complicated." Eric, Gia's husband. Bee, Gia and Eric's toddler.
