Partner problems

So I’m 21 and 6 weeks 5 days pregnant. Me and my partner have been together for 2 years and he’s 22. He was a state runner since he was 15 so when he turned 18 he never went out drinking or clubbing and all that stuff because he was training.

Now that he’s 22 he’s making up for it.

He doesn’t go out all the time, I’d say like once a fortnight but maaaan he gets drunk. He came home at 1am last night because him and his friends got kicked out of a bar for being too drunk, he was calling me none stop to pick him up even tho I said no because I had to be up early!! it’s driving me mad.

Do you think he’ll just be living his wild part of life and get over it? I mean, I was over it by 18 but we’re all different. I’m just hoping it’s going to stop before the baby gets here.
