Boundaries are something you do to define yourself. Conditions are what you set upon another.
I.e., you tell your child: If you do x, y, z, then a, b or c will happen. Condition.
You tell your spouse: I will not live forever in a sexless marriage. Boundary. Leaves all kinds of room for the other person to make decisions and choices. This defines YOU.
And that does not mean saying something of the sort is not unconditional love. You can still love someone, and not be married to them.
