This is one of those that's hard to speculate till we've walked in another's shoes.
Funny though - two of human's greatest complaints are loneliness - and never getting time to oneself.
I don't have any fears and always do face anything come to my way...About a friend who been that way as he needs to find a way to make him get over how he feels...as my niece close friend when used to sleep over at...was that way as can't sleep but closely with her and to be so closely to her while they were asleep...so just it is hard but getting over it will need both psychic and support as well to get over it.
Facing your fears rather than running from them is ideal. And although the comfort from his girlfriend has subsided his attacks, part of the rational is that it is an uncontrollable (without medical intervention, which he should be seeking) physical condition. That if he were to be alone with no help, the physical trauma sustained could be life threatening.
Uh yeah you should
You are much smarter than your boyfriend.
Systematic Desensitization is probably a good place to start....Nice user name BTW.
