Maybe you need to talk to ur BF about how you'd like him to react.
IMO men like to fix things & he maybe feels upset & wants to help...that ur crying Bec of something bad. So he wants you to stop & soothe you.

Maybe if you tell him to not act so quickly & maybe just comfort & hold you while you go thru it & that it's ok for it to happen, maybe he'll see it as something positive too.
