Alright so here’s the simple background:
I(33M) met my SIL(29F) when my BIL(31M) introduced me after he met her and basically said she’s the one. I got to know her over the course of time and had literally zero interest in her outside of her being my SIL by marriage. I am a brother in law by marriage because my actual sister married this guys brother. (BIL2) BIL2 and my sister and happily married and have a kid. Nothing out of the norm there.
Keep in mind, I am literally just a single dude enjoying life and I literally cannot understand how this happened so quickly next:
I went to my BIL’s joint bachelor party where at some point during the partying I was dancing with my soon to be SIL when she pulled me in and whispered in my ear “we would make cute kids”. I was laughing and said oh you’d have to have a thing for me then!? She answered “yeah I do but it’s just a crush”. Since that day her eyes were different. She looked at me different and I felt it.
