Hi Dalia,
Sorry for what brings you here. I know you care about your boyfriend. He has shown you that he cares more about alcohol then he cares about you. You have told him how you feel about it. It is up to him to decide if he wants to change. You can tell him a 1000 times your feelings about alcohol. It wont change until he wants to change. The longer he drinks it is just going to get worse. It changes the brain and he will always be wanting that next drink. He will lie and manipulate anyone that gets in his way of his drinking.
You need to look after yourself. You know what you will accept He has not shown you any respect in the way he has treated you. You deserve someone that treats you the same way that you treat them. Keep being strong and keep coming back here for advice or just to vent.
