[OOC] Return to the Rusty Rat

True but it's not about someone distracting you; it's about a deliberate action on your behalf.

Spell duration "concentration"

Concentrating to maintain a spell is a standard action that does not provoke attacks of opportunity.

When you made your first standard action other than concentrating on Dispel Magic (i.e. cast Spiritual weapon) you deliberately opted for releasing the spell you concentrated upon.

Regardless, it's a pretty good assumption that by exploring this small area without rushing headlong into any troubles took seven minutes, thus the spell wore off anyway. From this perspective this discussion is better conducted now than in a tighter situation where player characters or their wealth can be seriously affected by aborted concentration.

Okay you have right. In dnd 3.5 the concentration is broken if you take another standard action. 
More than one year I play dnd 5 where the concentration works a little different way.
