He was 100% in a relationship with dess in deltarune, no just friends relationship would result in a girl stealing so much of asriel's spare shit/clothes.
If a girl takes your shirt/hoodie and is super reluctant to give is back it's basically her saying she's your girlfriend now.....
Tho I wouldn't put it past asriel being anime protag level of dense, I've seen mother fuckers get introduced to the parents and everything and not realize their in a relationship until their girl asks when their gonna get married and or fuck
