Of course you are the problem, and the cause of all the hassles HE has.
God forbid he should look any further than at you, because then he would have to see that HE and his beloved drink are responsible.
I hate to say it, but.... this is only the beginning of the runaway alcohol train ride and it will get worse for you both. It gives me such sadness to see this hell for so many young couples, because it is such a terrible waste of what could and should be a good life for them.
Get all the info you can, get help for yourself by staying on SR, go to Alanon, get some counseling from a Drug and Alcohol Service, and above all DO NOT ACCEPT BLAME from him or anyone else.
God bless
