He has been waiting until 8 PM almost every night to call and talk to me.
If he's too busy for you then your relationship can't possibly work.
You'll need to tell him that your relationship goes two ways, and he needs to spend time with you. Tell him to set some time in order for the two of you to get together and talk.
I probably sound like a clingy, naive woman stressing out about a relationship too much. He seems to lack motivation, and if this bothers you, encouragement towards a future with you may give him more motivation.
If all he does is play video games all day be aware that will be his favorite way to spend time for years to come.
He also is probably used to girls chasing him instead of him chasing them.
