Feeling ignored....

So I recently started seeing this guy and we use to spend a bunch of time together. We now live together and he either works nights or mornings and then goes straight to playing video games or goes to bed. I get it because he needs sleep but I’m even looking to walk our dog together and just spend time talk about our days (which was something he suggest a while ago but we’ve never done yet.) He always claims he’s too tired to watch a movie with me or walk the dog but will game for 6 hours and then say it’s different or he’ll go out for drinks with his friends for 3 hours at a time because he feels bad for blowing them off. I just feel so alone... he’s always asking if I’m happy or if he’s doing a good job as a bf because this is his first long term relationship and I say yes because I don’t want to sound clingy. Is there anything I can do to not sounds clingy but tell him how I feel? I’m so depressed I just wanna sleep all the time.
