Should I still go to his show tonight?

So i met this guy last summer and we hit it off he asked for my number and text me that night to say he was glad we met and to get home safe.Throughout the months he would invite me to his shows,some i went some i didnt.Few weeks ago i asked him to meet me for a drink,he picked the place and picked me up,he stayed the night,we did everything but sex.That was 4 weeks ago,ive not spoke to him since,just his replies to my texts,and he is "so busy" with work,school and the band.He text me a couple days ago a mass text about his show tonight which is an important one to him.The thing is I know there is a list for the venue and im not on it,so i have to paay the 5 bucks,which is fine but the principle is I feel unimportant and almost like im a groupie. Am i? should i go to support his band or give up on him?
