Cheating

[Buglove]

I just discovered my sister is having a thing with a much older married man with children. So angry at both of them!

Is your dsis married and does she have dc too?

No she is a young emotionally immature 21 year old. Make me feel like its his fault. I don't know who or what to say anything too! Makes me so cross that people do this!

At 21, whether she's emotionally immature or not, she still knows what she's doing, she know's right from wrong.
Fair enough, HE is the married one and shouldn't have entered into an affair but she is assisting him in cheating on his wife and destroying his family, so he's not solely to blame.
Speak to her, maybe something you say will open her eyes before she gets in any deeper.

I do agree that she is just as much to blame and very cross with her. I will try and talk to her but she is so secretive an I fully expect to be told to butt out. I feel like contacting him and threatening to tell his wife!

Contact him and threaten to tell his wife.

Stay out of it its none of your business. Let her learn the hard way. He is the one cheating. She has probably fallen for his shite. It happens every day. I dont think it has anything to do with you.

Insightful as ever Wobbly

OP - it's really none of your business. They're both adults. Butt out.

Sariah affairs are SO awful and damaging that this is the one thing I would try and stop - before the wife finds out.

Affairs are about addiction. They are not about anything nice. They are about self-indulgence, using people, lying, and self-deceit. People who have affairs destroy a lot of things about themselves, too.

Her sis is being used, he is having a lovely fantasy about being free, and she is nice young and tight whilst wife has had some kids. Lets be HONEST here.

Once he thinks he will be outed, watch him run. Sis will find out just how loved and meaningful she really is to him.
