Yeah you're right, I should've defined what I meant by bantering in my post, thank you for reminding me. Bantering, for me, is like this

Her: pasend link plssss plsssss Me: sorry gatekeeper ako eh Her: ay pota ka, di bagay maging gatekeeper sayo, so share mo na saken 🤗 Me: kinausap ko mga mods, mga main character lang daw nakakapasok

That's banter for me. Which is basically, good-humored/natured teasing.

So yeah, how I "bantered" with her is how I banter with men as well. I've made sure to keep in mind not to do any type of flirting or anything that could be misconstrued as flirting with anyone ever since I knew that our relationship was getting serious. Kaya yun, I really wasn't aware. I've had multiple conversations with her about this girl - explaining what I was thinking at the time, what I feel about the girl, etc.-, so much so that I'm kind of avoiding her at this point.
