[subject] + 很 + [feeling verb] + [object]
[subject] + 很 + 有 + [noun]
[subject] + 很不 + [feeling verb] + [object]
很 normally goes before adjectives, but a group of verbs takes it too: verbs of liking, wanting, worrying, understanding. 很 then means "really" or "very much", and it goes before the verb, never at the end of the sentence.
The usual ones are 喜欢, 爱, 想, 希望, 担心, 怕, 关心, 了解, 同意, 需要. 很想 + person is "miss someone a lot".
有 with an abstract noun works the same way: 很有意思 "very interesting", 很有名 "famous", 很有用 "useful".
English puts "very much" at the end. Chinese puts 很 in front of the verb.
吃, 跑, 学习 and other action verbs can't take 很. To say someone does a lot of something, use an adverb like 常常 or a 得 phrase.
很不 + verb is a strong negative, "really don't". 不太 + verb is a mild one, "don't much".
