Letting your husband go to the bars

So this doesn't have to do much with glow but I needed some insight. My husband and I have spoken about how it makes us uncomfortable if the other one goes to a bar at night. It was a mutual agreement that we had for years so neither of us went to the bar without the other one. Well this year has been rocky for my husband and I and he has been going to bars at night until they close. Here I am, almost 2am and I am still up because I am worried sick. I am worried about him cheating. Now I know majority of women are okay with their man going to a bar... How do you do it!?!? How do you stay sane? 

My husband won't answer my calls or texts and I feel like I could throw up 😞 I need help not going crazy!! 

2:43am update: 

My husbands friend just showed up at my house asking where my husband was. I told him he hasn't come home from the bar yet. His friend told me that he left the bar 3hrs ago. Neither of us can get a hold of him. 

Seriously??? I am sick to my stomach!
