need help with this dream girl

For the last week I have been having a dream about the same girl in different situations, the weird thing is each time I wake up I feel sad and almost like I have lost something or let someone down, its a weird felling and even when I think about I feel sad straight away. (I am not going mad if that is what you think)

The dream I had last night was that the girl was going to get married to this old man, similar to an arranged marriage. Instead I said I would take his place, we went out and then when she found out what I had done, she got angry and then took off. I then managed to find her at this church on the hillside, I got her out of the church and then I was shoot before I could go with her.

Again I stress that it is the same girl in each dream, I don't know her name but it is almost like in know her or she is some sort of attachment to me
