Break up = (1) to end a relationship; (2) to break into pieces, or to separate; (3) in British English, to finish school before the holidays. Meaning 1 is the most common.
For a couple, it takes no object: add with to say who (She broke up with him). Meanings 2 and 3 take no object either. So it is almost never separable.
Both mean to end a relationship. Break up is a little more common and sounds stronger. Split up is more neutral. They broke up / They split up: you can use either.
A breakup (one word) is the end of a relationship. After the breakup, she felt sad. It is the noun that comes from the phrasal verb.
