Need some help...

Hi, I'm pretty new to this site and mostly joined because of my diagnosed bpd and needed some support.
However, I need some help or advice concerning some feelings that have been going on for me. Recently, I've developed stronger feelings towards my best guy friend and really have no clue what to do about it. We spend every waking moment together, and are so comfortable around each other that we even kiss goodnight. I'm afraid to tell him that I want more because I don't want him to leave me ( which is where my disorder kicks in). Has anyone ever experienced this? It's getting to the point that I'm jealous of every girl he talks to and want to tell him how I feel but I'm pretty sure he wouldn't want a relationship with me. Any feedback would be great!

keep kissing him goodnight and just let things happen, the fact that he kisses you goodnight is a good thing, now let me ask you this, is it on the lips or the cheek? don't say anything about the other girls..he is spending a lot of time with you.soooo....that means he enjoys your company or he wouldn't be around. let me know about the kissing & i'll advise you on what to do next!
hee hee..good luck!

Thanks for replying! And he kisses me goodnight on the lips and he does spend a lot of time with me...but we are good friends so I don't know if its cuz of that or something more. So what should I do!?
