Feeling very alone...

So long story short my fiancé and I have two kids 4, and 11 months. I stay at home with them and it’s already lonely. My fiancé is a nice guy he does come home and help with dinner and is sweet to me but around 8 he gets on Warzone. He doesn’t get home from work until 5:30. I feel like I shouldn’t complain because he’s sweet and stuff and provides for us. My problem is we don’t fall asleep together because he’s on the game. We don’t cuddle, have sex, hardly anything anymore due to him being on the game until 11:30 at night. One night he came in woke me up at 3 in the morning on weekend trying to have sex it was alright but not the best because I’m exhausted honestly from kids. I felt like he was expecting me to do all this stuff crazy but I was dead kind of like just “get it over with” type of sex.
