feeling lonely

Hello there,
I am in love with a guy who is very spiritual at the same time workaholic. He has no time for me, but other than that he is a great guy and I love him so dearly.It is the nature of his work and I totally understand and know he loves me too.
But I feel so lonely. I am involved in so many activities but in the middle of everything I feel lonely.I couldn't take my mind off of my man.
I pray for him and he prays for me too. what else can I do to not feel lonely without him
Thanks
