Boyfriend is ignoring me

So I've been with my boyfriend 9 months and he has been ignoring me for about 2-3 months. Before that I was getting mad because he kept blowing me off for other people even though I hardly got to see him. He said he had a problem with my attitude and said he needed space. I try to show him how much he means to me and how much I appreciate him and now he's blaming it on work, hospital bills, car repairs and still my attitude.
