Couples questionnaire?

Things between me and my fiance have been a little flat recently in the last 3-4 weeks, we are just bickering hes not spending much time with me mainly on his console after the kids are in bed till around 2-3am I go up to bed around 9:30/10 and he doesnt even talk to me (console is in our room). I know they may be his escape (in lockdown with a 10 month old and a 2 year old is pretty tough) but I dont get no escape or wind down time. As soon as i open my eyes in the morning I'm on my feet doing all the reoccuring jobs all day everyday then they are in bed by 7 and I'm cleaning up after the day, doing laundry, preparing things for the next day I probably sit down for an hour before I need to go to bed because I'm exhausted (they wake between 6-7am too). There isnt any intimacy, a couple of kisses and hugs here and there but in the whole nothing. I havent stopped trying, i try to initiate sex but hes not 'in the mood' I suggest for him to get off his console and for us to spend some time getting in the mood and he cant be bothered. He hardly helps all day all he does is ait on his phone and play with the kids on and off. (Before lockdown he worked as a plasterer but for obvious reasons cant do that for the time being so stuck at home and I was a SAHM). Its been a hard adjustment but things were alright at the start but now I think hes just slipped into laziness where as i cant I've got two kids to keep going for. I come across this couples questionnaire online recently and I've been thinking about giving it to him, you print off two copies fill them out one each and then swap answers and see where you're at see what you can improve and what the other person is thinking (if they are honest) it has questions referring back to the relationship at the beginning, and questions about it now questions about your sex life and loads more. Would it be weird to give it to him so we can both fill it out and swap answers as a starting point to figuring this out because I just feel like I've lost him a bit. And I think if hes getting the answers too he may be more inclined to answer as he will want to know what I'm putting. I dont know I just feel like it may be a conversations starter and just a nice way to remember how we used to be before the craziness of children, jobs etc came along. We have been together 6 years lived together for 3.5 years so alots happened we have been through a lot together. Do you all think this is a dumb idea? Or do you think we would benefit from it?
