Hello Now
If you reach out to someone, you extend your arms towards them – either to offer support, or to offer an embrace, or because you want support or an embrace.
In the song, the singer imagines a time when the girl might find herself in a state of despair or confusion. If that time comes, he says, she can "reach out" towards him, the singer, and he will "be there" to offer her support and shelter and "give her all the love she needs".
