You are asking about 3de persons feelings....not your own.
Your friends feelings will be colored by her opinion about you, over the time you both have known each other, and the feelings carried for the cousin.
Feelings is always in change, and the most important question for you, must be...What is my feelings for my partner? Am I true to her, are my action pure, or am I just playing around.
If your action show genuine care for the cousin, then I think you will win your friends trust,and approval, and if not.....maybe (S)he was not your friend after all.
Good luck.
