Luvmypups. (((Hugs)))
I see this is your first post on si.
May I welcome you to the club that no one wants to be a part of, yet there is no better place for you to be right now.
Also, as you post and receive recommendations, please take the info that matters to your situation and leave the rest.
Every poster here wants to help you but none have been in your exact shoes. But we all have worn the shoes of infidelity one way or another.
I personally have not been betrayed in the same way as you have, but I am dealing with a similar situation with my son's high level sport.
My son has played in his sport competitively since he was twelve years old. He has just turned 16.
His sport is considered a summer sport, yet my son plays, trains , trys out and travels all year long. 5-6 or 7 days a week all year long.
He played for his school as well since grade 7.
Plays for our capital cities team and has gone to nationals twice. Hoping this year will make a third time.
He has also played for our provincial team since he was twelve.
His nationals coach is also an assistant coach for the provincial team. So he is involved with training my son's teams all year round in one form or another.
Last year they made it to nationals. Before this my cheating radar was going off big time and my gut was screaming that the married coach was fooling around with the married team manager.
I was right and this spring, after he left his poor wife and she filed for divorce from her 'awful' husband, they moved in together and 'started dating'
These are discusting people and I can hardly stand the site of them.
But my son might suffer if I show it. He is a starter for both teams and is never subbed out. He is learning responsibility and so much more being a part of these teams, I'm so proud of him.
This got longer then I planned.
My point is that my son brought it up to me in June. I asked him what he thought of them dating?
He said he and the guys on the team don't believe that the dating was a new thing and he thought it was wrong and he lost a bit of respect for his coach.
My stomach tightened at that but it's not like kids have zero radar themselves.
It could be possible that your daughter already has an inkling that this has happened. Or her friends may know and someday tell her themselves.
Who should the information come from?
I send you all the strength I have to give you.
