Just let it slide or?

My boyfriend & I are 22&21, we have an almost 2 year old plus another on the way. I let him have some beers tonight with his cousin, I went to bed at 11. I asked him when he’s gonna come to bed, he said 2. I woke up at 2:30, and waited lol needy😅 It’s now 3 & I went to check what was up & he took off. 🙄 We don’t live here in town anymore, we literally just got here on Wednesday. He talked to a lot of girls here. My anxiety is through the roof.
