The rules of gustarse are a bit confusing. Here's how it breaks down:
The first thing to keep in mind is that you can never say "Yo me gusta algo." The verb to like in Spanish literally translates to "___ is pleasing to me."
<u>The pronoun in front of gusta always corresponds to the subject.</u> When you say "A ti te gusta ir de compras" you use the tu form of the pronoun before.
<u>The gusta part can be either gusta or gustan.</u> If the things you like are plural, use gustan. If they are singular, use gusta. Don't ever try to translate them the usual way by saying "gusto" or "gustas."
