90s indie rock song ID

This was taped off college radio in 1996 (after a Hush Harbour song, ha!). It's fairly upbeat, major-key sounding, v anthemic, with a droney, bright, trebly buzzy guitar sound, fairly standard song structure. The voice is male, tenor, slips off-key when he strains in his upper register in that indie rock way. It's mixed about as loud as the guitars so it's a little hard to make out most of the words. The first word appears to be "serious". The pre-chorus goes something like "But do we ever go outside anymore?/The air in here is . . . away /Do we ever go outside anymore?/The air in here is fine". The chorus goes something like "I let you live inside my (house?)/You couldn't leave anyway/I'll build you up till you are strong/Till I can breathe anyway/Till I can breathe anyway". The second verse starts with the line "If the world could self-destruct/(It's nothing special?)". Then there's a slower part where "self-destruct" gets repeated a couple times. I really like this song but never really tracked down it's ID for a long time. My resident indie expert in Montreal couldn't help so I'll be eternally grateful if you can.
