Dear Sweet
Your latest post tells me that you are strong enough to get out of this nightmare because you are seeing the lies more clearly – it takes time for the lightbulb moment but I suspect that your light is now well and truly switched on.
How he will pay his debts back is his problem Sweet, not yours – you did not make the choice to gamble, he did, you did not lose the money or run up the debts – he did. Yes, it is hard for him to face his demons but he can do it if he wants to enough and I have not heard once, in all your posts, that he wants to control his addiction enough, for himself, or for you.
If he books his ticket Sweet and makes a wasted journey it is his problem – maybe you could ask your father to speak to him on your behalf. If his brother has covered his gambling losses then that it is his problem.
Why do you feel you ‘have’ to speak to him? You are a free woman, you do not ’have’ to do anything.
Stop the destruction of your life Sweet, live in the light and enjoy it.
Velvet
