Communication issues 😣

I’d say this is our biggest flaw in the relationship. It’s extremely frustrating. I’m 7 years younger and I tend to text and tell him what I’m doing (if I go somewhere or take our son somewhere). BUT he doesn’t do the same. It could be HOURS and I have no clue where he is. Then he makes little white lies and I catch him every time. For instance, tonight our son was asking to see him all day! He worked till 5 and told me he was on his way home. He then calls at 530 and I knew something was off. He made up some story about seeing his family and he ended up being at a bar with his worker. I decided to shrug it off. He said he’d be home around 7. WELL it’s now 10:13 and he’s still not home. This is not ok with me. It happens quite often. We’ve been together 3 years and I don’t understand why t doesn’t cross his mind to tell me what he’s doing. Don’t I deserve to know? I felt so bad I promised our son he’d be home tonight. Sometimes when I bring up the issue he says that he’s just older and doesn’t think to text me everything, that that’s something younger generations do. I’m sitting here very angered. I made us dinner and kept my son up .. waiting and waiting. So disappointing. 😔 I’m afraid he’s going to come home trashed and won’t even be worth talking to tonight.
