I NEED TO BE WITH HER NO MATTER WHAT?

ok long story i met a girl named linda in september who was desperately attracted to me and i did not like her at first soo i would always blow her off. eventually one thing led to another and i started hanging out with her and i really started liking her and we established a close relatiionship but were never officially dating like we would hug alott. in a couple of weeks we began growing apart but i still was liking her alot so i didnt hug her or really talk to her until christmas eve when she told me i looked handsome and gave me a bunch of hugs. and we then begaan going to the friend zone even though i didnt want to we went on being friends and sometimes i would kiss her on the cheek or we would watch a movie and she would put her head on my shoulder and no matter how much time passed my attraction to her never faded. Now within the last few weeks ive began seeing her friend and we have been pretty close and i are sorta dating. and i thought i was over linda but then we hung out alot lately and even went to an amusement park togethor and that stuff . and she did somethinng really cool for me so i would look good for her other friends. and now im fully attracted to her more then i ever have been what shouldn i do i dont want to hurt her friend and what can i do to get linda
