I have grown into a habit of stepping across my stumps to front foot shots in cricket,

[Graeme Dale]

how can I stop this? Just in the past month, people that I play and train with have been mentioning that I step across my stumps to play front foot shots in cricket. I have been bowled a couple of times at training because of this and I am worried it may happen in a game. I have never done this before and I am worried it will affect my game, how can I fix this?
