Can my boyfriend have an alcohol problem?

If you have to ask..: You've already read online about signs of a person who is losing or about to lose self-control with respect to alcohol. If this fits the picture, you have my sympathy and don't let your emotions keep you in a relationship that will ultimately make you miserable. If he drinks occasionally, this is not a sure sign of a future problem though there are people who'll tell you this. Be discerning.
