Yes they are not lying but they observed what they wanted to see. Our mind plays tricks and it will show us what we want to and will let us hear only what we want to. If you show this picture to people some will see a pretty young
woman and others will see mother in law based on their personality makeup.
They just want to hurt you and get amused by telling the stories of your hubbies past. Real sincere friends will not do any such thing. Will you do that to your good friend ? I guess not.
If it was going on in the present then it was something of concern.
