My sister was widowed two years ago with two kids. She has been depressed and suicidal. About 6 months ago my husband offered to take her two kids swimming once a week. About 4-5 months ago my sister’s mood started improving.
I knew my husband and sister were close. But recently I saw explicit messages from her on his phone. Reading through messages I realised he drops the kids home and once they sleep, they cuddle and have sex.
The actual off my chest is I don’t mind. For the first time in years my sister is back to her usual self. If I need to share my husband to get her back, I don’t mind
