Father figure in a professor?

Through the years I developed a good relationship with one professor (a thesis mentor) on the faculty. I finished college already but I still have a little bit of contact with him because we are finishing a research paper together. I realized that one of the reasons that I like working with him so much is probably that he sort of represents a father figure to me (this realization shook me to my core, and it took me a while to process) since I never really had a father. He is a very nice and caring person overall and a lot of times went out of his way to help me or give me an advice.

I am lately thinking a lot about the fact that when we finish this paper, which will be very soon, I will probably never be in contact with him again. I don't want this to happen, since I think that this relationship is giving me something very special. I don't really know what to do about this or how to resolve this internal problem within myself.

Do you have any advice or thoughts about this? Thank you!
