Ok im really struggling here my friend 'Kate' 19F and Myself 19M have been close for about a year (though she says a bit longer) so something awful happend which ended her last relationship which has greatly impacted her mentally and this has had physical repercussions as a result despite this ive tried to be the best i could be and I am by no means a good or moral person ( Heavily involved in drugs at one time) She knows about some of this but hardly anything bad. Ive always had a soft spot for her whether it be when it comes to her begging for something or her wanting help with something and as of late ive developed feelings for her feelings that i had kinda had before but interest faded and came back. I feel like a arsehole just for thinking about her like this because technically I have known her for 10 years and she has said im like a brother in a way before. Im really bad at picking up signs but shes become kinda interested in my dating life for some reason and kinda draws away if i mention something about another girl. Given that shes in a vulnerable place i dont feel as if its good for me to think of her romantically especially cuz she is very open about SH and eating disorders which have obv taken a toll.

So AITAH?
