Not exactly my SIL, but close enough. This in regards to my Ex and her cousin, who is almost like a sister to her.
So my now recent ex, Amanda who is 28 (I’m 28 as well), has an older cousin who is 43, her name is Christina. Christina is very attractive and educated but has been single for as long as I had been dating my ex (4 years).
From the moment I first met Christina I was extremely attracted to her and I feel like she knew. I was somewhat always reserved and slightly awkward around her due to the fact my attraction was so strong I never wanted to make it obvious to either of them that I wanted her.
