Fuming!!

So I’m too angry to get in to back story! But trust I have reason to feel the way I do however I would like to know others options. My partner works away a lot. When he took the job he said he would still call and message and I said no it’s fine don’t worry. But he did anyway he would call every night and message before he went to sleep and always making sure we was ok. Until about 5 weeks ago he stopped ringing and said he didn’t have time because of going for showers and food but then he would message me until about 8ish and either not message till the morning or message about 11.30 saying goodnight! Then tonight he did the same message me at about 8 saying he had just finished his dinner, I replied and he didn’t so I left it till 10 o’clock and I said I know your busy and away but you could at least message saying goodnight! He rang me straight away and said I was just about to ring you (Bare in mind he hasn’t rang me when he was away for the last 3 weeks) so he was in the hotel room and said the other boys are down stairs he went down and was going to go outside but said to them “fucking hell another 2 pints” And a woman replied “so what ahaha” my partner then said to me on the phone oh just one minute and put the phone down! 15 minutes later he rang me back acting like it’s all cool! When I said what bothered me he acted like a dick and said what do you want from me I’m at work and I said so sitting in a bar drinking with your mates is work is it and he replied with yes!! Are you fucking kidding me!! Anyway I’ve had messages from girls previously saying about he messaging them but never any proof but how he has been acting the last month I’m ready to pack his bags!! Would any of you feel the same??
