Feelings for my best friend and not knowing what to do.
I (32 M) started to have feelings for my (39F) best friend, I know her for about 6 years , the first 4 years were nothing serious but the last two we started being more intimate and vulnerable with each other. She was in a previous 10 year relationship with another but he left her and she tried to date ever since but had only disappointments . Some times when she was /is feeling down we hold hands together, we even sleep in the same bed when we go on trips with friends or just the two of us, we do plans on what to do for the next weekend or in the summer, some of the times she said that she would prefer to be with me in the car rather than someone else. Recently on the last trip she had a panic attack on a hike and we held hands and i comforted her the best i could and at the end of the hike ,when i was taking some photos , she kissed me on the cheek thanking me for being there for her and also the next morning (we were in the same bed)when we woke up, she was playing with my hair.
On another occasion i told her that i will go to a concert and she asked me if she can come along although she doesn't really like the band.
Now i really don't know how to interpret this, on one hand it seems obvious that she may have the same feelings for me, on the other i keep telling myself that I'm not good enough for her (she has a better financial status, also the age...and she's a bit taller than me) and that she only sees me as her comfort pier, not a romantic one.
What would be the best thing to do ? I want to tell her ,to have a full disclosure, but at the same time I'm scared of not losing her or making the relationship awkward.
Also sorry for any misspelling, my English is a bit rusty.
