Ive got this female friend with who ive been friends for about 4 years. She didn't show intrest in me until recently. Whenever we go out together ( not a date, we go as friends) she likes to hold hands with me. She also sometimes sits in my lap (even when in group, i was talking to some other girl and she just casually cane and sat in my lap.) Now I don't know what to think, I dont even try to flirt with here. I would have sex with her but not anything more than that and im afraid to ask her cause it can ruin our friendship. What do you think?
