i dunno - for me the relationship is "safe enough" when you find someone you can trust (or maybe just want to trust) - regardless of the risk.
my T is such a person. i trust him completely. but his is a professional relationship - which puts it in a different light.
And, actually - it's not completely bad. alone, isolated, yes ... but no fear of someone taking advantage of the friendship. or worse, once you become their friend they tell you that in order to KEEP that friendship, you must now accept the tripe they spew...
Anyhoo - still think it is better to be hurting from being alone rather than hurting from being abandoned.
