Okay, lover of long hair and furs here; love enough that the professionals would call it an obsession or a fetish. May sound harsh but the brutal truth is deal with it...you're gonna survive too.
You've had a breakup and those suck - especially if it is someone you loved and care about. Yeah, doesn't help if she had certain qualities you loved more than others (hey, if it isn't hair it's tits, butt, smile or something else).
As for you've only got one other friend...relax and expand your horizons. Unless you are condemned to die in the next 3 weeks you have a chance to meet someone else.
Now let's talk about that someone else. You may meet a long haired lady anywhere - keep your eyes and options open! You may even find someone with short or medium length hair that suddenly "decides" to grow her hair longer...all because she is interested in you.
And let me just say, you can find sexual fulfillment even without one or more fetishes being realized. I've been with women with short hair and no fur coat or jacket for miles around and had mind blowing, body exhausting sex.
You're gonna be fine, just take a deep breath and live!
