choices

Do I listen to my head or do I listen to my heart??
My head is telling me to give up and move on! If I continue trying to be with him then I will contiue feeling alone and not know when the next time I will hear from him and I dont know if I can live like that!
My heart is telling me give him one more chance! I do love him and I want "us" to make it! I just dont know how much more I can handle.
I have some major thinking to do and defintly have some choices to make.
Do I liaten to my head or my heart??
