Hello, all. Is it a general rule that if I have specified myself with a previous conjugation, then an action after the fact would be the infinitive?
For example, if I said to my girlfriend in so few words "te ayudo", I'm saying I help you. However, I can't figure if it would be correct to say (to someone else) "tengo que le ayudo (a ella)" or, "tengo que le ayudar (a ella)". I feel like it should be "… le ayudo" but I also did clarify myself with "tengo", and so "…le ayudar" seems right too, so I'm unsure.
If I've made any other mistakes in this question, I apologize, I'm a noob.
