In our family we have a rule, If you start something you finish it. There have been times with all of our children and they play soccer for two different clubs, that things were not going the way they had expected. You finish the season out period. Respect your club,team,and coach. There is no issue if you want to change teams or clubs after the season is over. They have the right to go where they want and feel most comfortable. There is always going to be someone to take their place and the team and club will go on.
