Any punk rock songs about friendship or never leaving each other?

There is his guy and we became really good friends after we met at homecoming this year. We became really close, then we dated for about 2 months. I was the girl and I was a little taller than him and we didn't like that, so we broke up. Stupid, yes I know. But now we are best friends and we care about each other so much. We have always helped each other and it is obvious that we still have feelings for each other. It is more of a deep compionate friendship. Me and him both like the pop punk, rock, alternative, scremo music. Like blink182, 30 seconds to mars, devil wears parada. stuff like that. Are there any songs in those genres that are about never leaving each other, or wanting each other, or compion for one another? He is my everything and so special to me<3
