What does “I’ll wait for you” mean?

Help my friend decode their dating life. lol

Context: A man and woman are interested in dating but the timing is not right. The man is in the process of ending a relationship. The woman says “I’ll wait for you.” The man didn’t ask what she meant by that and the woman didn’t clarify. That was the last time they talked and agreed to not talk again unless they are both single.

What do you interpret the phrase “I’ll wait for you” to mean in this context?

Does your answer change if you knew the woman said she would wait 1 year. Does giving it a time frame change the meaning?
