The bloody cheek of him, using your expensive Sky while he doesn’t even deign to communicate with you.
Sorry this is so hard OP.
I must agree I think you need to take control and dump him. He clearly thinks women are there to facilitate his life, he should be able to drool over semi naked women when he feels like it, eat off their grocery bills, use their hit water, use expensive Sky packages installed for their particular need.... but god forbid should he be expected to pay, or listen to how any woman is feeling, apologise or give any commitment.
You can’t win. Tomorrow, if you ignore him he will turn that back on you, probably even say to your Dd ‘your Mum isn’t talking to me’. If you are nice to him he will see it as you capitulating and take it as you apologising in kind, and ‘reward’ you by paying you attention and resuming communication.
This week he has given you the silent treatment, said ‘it isn’t working’, refused to answer the door to you, ignored your good luck message, declined to tell you how it went, and continued to ignore you while using a Sky account paid for by you. And he either wasn’t in to watch Black Mirror (where was he?) or he was so determined not to contact you that he would rather miss it than contact you to say ‘is there something up with the account?’.
And yet you are dangling on a string, wondering if he will apologise or approach you.
He is treating you very badly. He either really does want the relationship to end but is too cowardly to say so, OR he is punishing you for saying you were upset about him ‘liking ‘ bikini shots of other women while you are away / in your absence. He is trying to make sure you never give him any of your ‘shit’ to listen to ever again.
Or then again, he might really be turning away from the relationship. Since he didn’t answer the door or acknowledge your good luck message.
Take control OP: dump him.
Tomorrow focus on your children, chat with other people. If you see him and he sees you, smile politely and then give a little wave and take a great interest in something across the space.
If he says ‘are you ignoring me?’ Say calmly “ if you want to talk to me about your behaviour this week, call me later. This isn’t the time and place, Ooh look, there’s xxxx, I must go and watch / talk to them “
