I've been following along, cheering you on from the sidelines, but have NO advice or helpful suggestions when it comes to dating!!
With the SIL question, no, it is not weird. In-law relationships do not end b/c the marriage does. She will always be your sister if you choose. My step-kids will always be my stepkids, H's cousins will always be my cousins, etc. The beauty of the situation is that you get to choose which relationships to maintain. YOu can let go of the H's crazy relatives and keep the ones you want. This is best for S as well. It is great you have a good R with his aunt! and his cousins.
My Mom and my Dad's sister did become like sisters. When my parents D'd, that R suffered a bit but recovered. Had it not, I doubt I would have seen my Dad's family at all or had any kind of R with my cousins. It is us women who maintain such ties.
