I believe this song is written about his wife and how their relationship has kept him from committing suicide and given his life meaning.
He talks about how he contemplated suicide frequently (letting all the blood flow out), until he met his wife. His wife has made everything better in his life and given some kind of meaning to the suffering he's endured (Can I just say how worth the wait it's been? / Can I just say that I would do this again?).
She's convincing him to stay with her, or keep from committing suicide because their lives have meaning now, they love each other, and she doesn't want to lose him (And now you say, say, say would you just stay, stay, stay. / There is a point to all this, there's a point to me. / There's a home I have made in your heart as it beats).
Dan would endure everything that he has if he had to do it all over again (Because now I know I have you in the end).
