night clubs

My boyfriend has hit the legal age just under a week ago and he's going clubbing for the 3rd time. He told me he'd only go once until I'm legal to go. And when he goes he completely ignores me and doesn't let me know he's safe and blocks me out from hits before he goes to hours after he comes back. I know he's with the boys and can't talk but I should at least get a reply if I'm asking if he's safe ? Like it's not hard to send me a quick and little message right ?
