The defence mechanisms to be used in
this case would be:
- Denial: Better is to not
acknowledge a feeling, that would make a person vulnerable to be
hurt. Here, the people who might be hurt by these feelings of mine
would be me, my best friend and to some extent her partner, as they
would be trusting me. It would help all three of us for me to not
accept the fact.
- Repression: in this mechanism, I
would tend to block my thoughts unconsciously, so that I would not
act on my feelings.
- Rationalisation: where I might want
to redirect my thoughts looking at them through a different
perception, such that I was having romantic feelings since maybe
even I want a romantic partner, so that my thoughts towards my best
friends partner could be mitigated.
