My “husband” and I have been separated fir a year, because he cheated on me for over 2 years and then I found out. He has the same girlfriend now, but every time I see him (because of our daughter) he tries to get close with me, tries kissing me etc. Of course I’m not having any of his shit, but recently my SIL told me that I should make his girlfriend aware of what he’s doing. I don’t give two fucks about her, she knew he was married with a little child when she started messing around with him. Now she thinks they have the perfect relationship, she just doesn’t know he’s still trying to get into my pants. So am I really obligated to tell her? Shouldn’t she know that her boyfriend is a piece of shit and will do the same to her than he did to me? I hate both of them so I don’t give a shit about any of their feelings, but my SIL makes me feel like I own it to woman (not like she didn’t to me 🙄). What do you think?
