Learn Finnish: Poikaystävä auttaa minua paljon.

Minua is the partitive form of the personal pronoun minä (I). In Finnish, the verb auttaa (to help) is a "partitive verb." This means that the person or thing being helped must always be in the partitive case.

The English translation says "The boyfriend", but I don't see a word for "the". Why?

Finnish does not have articles like "a" or "the". The word poikaystävä can mean "a boyfriend" or "the boyfriend". You know which one it is simply based on the context of the conversation.

Is poikaystävä made up of two different words?

Yes! It is a compound word made of poika (boy) and ystävä (friend). Finnish uses a lot of compound words, and they are written together as one word without spaces.

Does the word paljon (a lot) have to go at the end of the sentence?

Usually, yes. In standard Finnish word order (Subject - Verb - Object), adverbs that describe how much an action happens, like paljon, naturally come after the object (minua).
