My Humble suggestion......
My suggestion is that U find out who among the Two ( Girls) loves U ( cannot live without U ), U should should develope UR romantic feelings with Her, with the other only friendly relationship......
UR life will be more happier with the one who loves U better, rather than with the one whom U love ( bcos U may be forced to make lot of unwarrented adustments throughout UR life for her - ultimately driving away UR peace )
BUT The one who loves U ( who cannot live without U ), has already accepted U as U R and will require minimal changes to make - ultimately presevering UR Identity and peace of mind.......
It may sound selfish ...... But its be wise...... no gamble with LIFE ...
