Boyfriend question...

If your boyfriend or significant other kept going out every other night to sit at a bar with his friends and he knew for a whileeeeee that you didn't appreciate him doing that all the time and coming home at 2-3am every time he went out...even 2 or more nights during the work week, what does that tell you? It's ok to go out every so often with your buddies....but 4-5 days out of the 7 and coming home in the AM every time?? What would that say you? I'm curious of your answers bc this happens to me and has been happening for a year and there's no change. Thanks for your responses!
