MD affecting personal relationships

Hey, my name is Bridget!  I am new-ish to this community but I am definitely not new to maladaptive daydreaming.  I can remember doing it back when I was 10 (I am 21 now).  I definitely used it to cope with loneliness that I experienced as a child, teenager, and even now.  One thing that is new for me though is the prospect of being in an intimate relationship with someone else.  I do have someone in my life right now who I know wants to be in a romantic relationship with me and I have to say that I am very scared of entering into that and have had a difficult time feeling the same way about this person.  I like this person as a person but my DDs involve a long-time spouse so I feel very attached and loyal to that character.  Anyway, I think since I have been doing this for such a long time I have transferred a lot of my emotional attachments to my characters instead to people in real life which used to not be an issue since I never had any dating prospects but now that I do I am finding it difficult to move on from it.  I was wondering if other people felt the same way or how people in intimate/romantic relationships cope with having a partner in real life and in DDs.
Thanks for the help!
