I'm with a SD that claims him and his wife are "separated" but he's still maybe trying to work things out with her. I didn't think I'd be this jealous, but every time I see her pop up in his social media I get insecure :/.

Sometimes the jealous side of me thinks I could absolutely destroy any chance of him getting back with her if I reached out to her and told her about me, but I'd never actually do that. Even though I didn't know this all going into the SR and only found out after developing feelings, it is what it is, and I need to keep my own emotions in check because they were never supposed to be this strong in the first place.

Legal matters regarding the separation don't quite phase me because I'm so far removed from their immediate lives that there is no way she should ever find out about me (we live thousands of miles away). To the same extent, the details of their marriage are also far removed from me so it's possible I'm being lied to a ton and am purely just a side mistress of an otherwise normal marriage.
