I don’t even know what to call this!!

Last night a bisexual friend confided in me that although married she has fallen in love with someone else, that someone else is me, to be honest I have thought this to be the case for about 2 months now. I’m lesbian and I have had feelings of love for her for about 12 months now but I have repressed these feelings as I often fall in love with my friends after a while of just being friends.

From what I can see and understand she is not unhappy in her marriage she just wants abut more fun and affection in her life.

What do I do? What do I say?

It’s hit me really hard. I don’t want to potentially break up a marriage but I want to make my very good friend a woman I love and cannot live without as happy as I can. Iv been waking up and crying all night.

Advice please.
