Should my partner have cancelled his plans?

So I've had an issue with my husband going out way too much with his friends for about a year, a year and a half. We have 3 kids under 3. We're both under a lot of stress and pressure and it's hard doing this 3 under 3 thing alone with no help and financially a bit unsettled too. I understood that so let the going out loads and blowing off steam thing go for a while. But it just became too much. my partner works 4 day shifts 4 off 4 nights. So in dav shifts I take care of the kids completely alone not a soul to help for 4 days straight, when he has his 4 off i obvs want to spend time with him once kids are in bed. However he began going out 3 if not 4 of those nights . Till 2 or 3 in the morning. I eventually lost it and after months of arguing got through to him. He stopped for a few months. And now it's started back up again. Because he was adamant the times before he was in the wrong and he would change. Now it's started again I'm not okay with trusting his word anymore. I feel like I should leave the relationship and find someone who actually wants to spend their free time with me and not their 5 different friend groups. I don't think I should have to fele like oh wow he chose to spend tonight with me and not them. This holidays his plans were to drop me to my mum's and spend every night with friends. My parents decided to visit us instead. For a week he was being horrific. He was causing massive arguements swearing at me just being awful. I sat him down and said have it out. What's wrong. He said sorry but my point was what is wrong. He eventually after hours of beatung the bush said he thought he was gonna spend this holiday with some free time away from me and kids and with friends. Obviously I was hurt af. I was so hurt I said okay then look you can still have some nights out with friends. And then the holidays have come and he's spent only 1 night at home with me and that was because he was working that day. Today morning he wakes up and says I'll take the kids. He then lazes about all day and then around 4 I tell him we'll bath the kids , feed them and get them to bed by 7 early so we can have a nice night. He springs on me, I've got plans at 7 with the boys. I lost it. Told him I'm leaving him he thought it was a massive joke and once I looked into the logistics of travelling cross country with 3 under 3 alone to go to my mum's and saw it wasn't feasible without asking for help I started crying , feeling so trapped in a relationship with a man who puts me last. He saw me sobbing and ignored it. He asked me whilst I'm crying to help him bathe the kids. I did. He then showered and got ready and left to go out with friends even with me telling him clearly, if right now u chose friends over me I'm emotionally done with you. He left. All the while saying I'm sorry I know I'm being a shit person I will do better YET HE STILL WENT . Help. Me.
