Traits of someone who is an alcoholic ?

My boyfriend can handle so many drinks do to a high tolerance I’m assuming so he doesn’t slur his words and isn’t falling over like Iv seen in tv etc.. but he drinks so much almost everyday and starts early in the day. He can drink an entire bottle of wine, 6 packs a bottle of bourbon or whisky.

Am I overreacting to think this isn’t ok ? Is this normal ?

We have a baby and I don’t want her to grow up seeing him always drunk.

What are some traits anyone has had experience with
