Welcome to SR anonuk.
There is a special section for Friends and Families of Alcoholics where you may also get some answers so you may want to ask this same question there.
What is your boyfriend planning to do now that he has recognized and admitted he has a problem?
If he is not planning on quitting drinking it will likely get worse.
If he is planning on quitting you may suggest to him to join here and he will get the help and support he needs to be successful.
Good luck to you both.
