advice?

So my boyfriend and I have been dating for about 10 months
In September he had some college applications to fill out and homework to do that gave him less time for me. Now it's still going on, but he no longer has college applications and he has less school work 
He mostly plays games but still dies not give at least a little of attention to me
I've had many conversations with him before but nothing has changed 
He hasn't been able to hang out lately, and when he has had time he'd rather sleep or play games
Today, was a half day of school
There was a weird lining on my leggings from the way I was sitting from my underwear so he asked me which pair I was wearing
Apparently he really liked the pair I was wearing and wanted me to come over
But before then, when I asked him if he wanted to hang out he had things to do
