hey. yup, that sounds like transference to me :-)

yeah, it sounds like a great thing to be talking to your therapist about :-)

re: what it means... i imagine this person has become an 'idealised (m)other' who met some of your emotional needs that weren't adequately met when you were a kid.

regarding how you make it stop...

the usual notion is that talking to your therapist about how you feel about this person... about how your mother never met those needs... should help.

that is the idea anyway.
