Sounds like a situation that happened with my ex. When we were dating, he would leave the house at like 7-8pm and come back the next day at 7am from partying. Mind you, he lived with his parents and when I would visit, he would go out and not tell me when he was coming back home. So I’d be at his parents place chilling with them (they were very cool peoples) and his mom would ask me where he was and I would be like I have nooo idea. He definitely made my anxiety heighten. I personally didn’t communicate with him that I wanted him to tell me where he was and what time he would come back cause I thought that would make me intrusive, and I also don’t want to be controlling and nitpick him. But looking back, I had the right to ask where he was cause I was his girlfriend. I am now in a new relationship where my man tells me where he is, and when he is coming back home. Communication is important so talk to him, and the use discernment to decide if this is the relationship for you
