Help Me Understand

I am at a loss and I do not know what to do.
Lately, my husband has been going to the bar without telling me, or he does tell me, with the caveat that he will be back in “an hour.”

We work different shifts, we haven’t had time for us, in a long time.

Tonight, we had time to hang out and talk, had some drinks and we were reconnecting, but when I said that I was tired and I was going to bed, he said , “Okay well I’m going to go to the bar.”

…Why? Am I missing something or am I not enough?
