How do I approach the situation?

My partner has a drinking problem, as much as he likes to deny it.

My partner has admitted before he relies on drink too much and has tried to go sober may of times, but each time he’s lasted a couple weeks then caved in. It would start off with him saying “1 bottle at the weekend won’t hurt, I just need to cut out the weekday drinking”, then he would start drinking during the week when his favourite football team are playing. Then before you know it, he’s drinking 2/3 nights a week again.

We recently moved in together and this week he’s had a drink Wednesday because it was “a stressful week”, Thursday because “his team where playing”, Friday because “he was building our coffee table and that requires a beer”, then all day today because he’s out with his friends.

I don’t know how to approach the situation by telling him I’m noticing a pattern in his drinking again and I’m getting worried. We have a baby girl due in 10 weeks and I don’t want him drinking 3/4 nights a week in the house.

Help!
