I've packed his bags!

So he's done this before. When he goes out he acts like hes never tasted alcohol before and that he can't say no to it. He's 34, has a fiancé, a house and ttc. He went out tonight for a leaving do, at 6pm. It's now 3.40am and he said he fell asleep at a mates house. He didn't tell me he was even leaving town to which he should have just come home. He has work in 6 hrs. So he has that amount of time to sober up before getting in his car. He acts like a teenager with no responsibilities! Like I said its happened many times before but now, at 3.40am I have packed his bag and chucked it by the front door. A relationship wasted. Am I right in doing this?
