That sounds tough, but whatever your days off, though they may vary, you can at least plan to spend time with him when possible? Maybe if watching TV isn’t possible, what about the cinema? I don’t know what I would do, but some kind of plan written down might help. Do you get many weekends off? How about annual leave? Maybe if you are able, a few days away in school holidays could be really good for bonding. I really hope you can both get through it, hopefully once you get a place sorted things can improve.
