I recently had an affair with my sister husband which makes him my brother in law.. I know I had crossed the line but he promised me the world and I gave everything up for him.. I lost my entire family for him just to decide that he was going back with my sister, I truly believes he dose not love her but they have grand kids together, so he wimped out and went back.. Last week one night everything was perfect and the next morning he said he couldn't do it anymore... what can I expect from him?

More of the same. That's not hard to figure out. How are you, and your sister doing? Interesting your more worried about him, than your family.

You must have known that you were seriously breaking all the rules of honest decent behaviour-and then the cheating husband did what they most often do-he went back to his wife and family.
Though why she'd take him back I can't even begin to grasp.

I have no idea what your relationship with your sister was like before you thought it would be a good idea to become involved with her husband, nor do I know if any bridges can ever be rebuilt.

I think you got exactly what you deserved.

You cheated, with another man, who, unbelieveably, is your brother in law!!

You wonder what you can expect from him, and I'd be wondering about how quickly I could get into counselling to figure out why I did what I did. Then I'd be spending as many years as it takes to try to make up for this horrible thing you have done to your family.

Yep if your not sure if you crossed the line then you have bigger problems then you think.

Hope your not pregnant. Well I agree things like this does happen but your left eating sh!t and it is your own fault.

Now learn from this and you defiantly need to learn what is crossing the line. This is more then crossing the line. You and this other person destroyed a whole family. The effects of this will be life long.

Time to change your ways and learn from this and start over again. Without messing around with anybody.
