What is the difference between to and for?

'To' is used for direction (go to school), purpose with an infinitive (I came to help), and indirect objects (I gave it to him). 'For' is used for purpose with a noun (I came for help), benefit (I did it for you), and duration (I waited for two hours).

Is it 'thanks to you' or 'thanks for you'?

Both exist but have different meanings: 'Thanks to you' means because of you (often negative: 'Thanks to you, I missed the bus'). 'Thank you for' is used before a noun or gerund to express gratitude: 'Thank you for your help.'

When do I use 'for' vs 'to' for purpose?

Use 'to + infinitive' for purpose: 'I went to the shop to buy milk.' Use 'for + noun/gerund' for purpose: 'I went to the shop for milk.' / 'I use this knife for cutting bread.' Both express purpose but use different grammatical structures.
