It's not a male/female thing at all. He's telling you that he doesn't want to be your therapist/rock/Mr. Fixit. Your job is to accept it and continue with the relationship or find someone else who will willingly give you what you want.
I know this because I (a female) used to be a little helperbug/Janie on the Spot. Listening to problems, going out of my way to fix stuff for people, kissing any and all boo-boos. Not because I have any sort of martyr complex, but because it's just nice to be nice to people--I think it's the way to be. Problem was, I was overloaded with people depending on me, and I found I wasn't able to pull back out of these one-sided relationships without causing *major* drama (Whyyyyyy do you hate me now? What did I doooooooooo?) So I decided (with much guilt, btw) that I just needed to not let people latch on in the first place.
A major turning point was reading an article by Martha Beck which talked about "emotional sl*ts". She pointed out that these people will just move from person to person to person, getting deeply emotionally involved with anybody that would have them, and that they will absolutely recover from being rebuffed and go find someone else. My MO, then, when someone wants to get inappropriately emotionally involved with me is to give a response much like the one your boyfriend gives you--"Wow, sounds like your boss is horrible. What are your options? Oh, your mom shouldn't have said that to you. What are you going to do to change your relationship with her?" Detatched, caring, but with a distinct "Yeah, no, not going to fix that for you. Please quit asking."
Not that you are being an emotional sl*t. (Or maybe you are.) Just know that he's just setting a boundary with you. He might be afraid that if *he* starts *you* won't stop. It's up to you to quell his fears. Because really, when you think about it, asking someone to listen to your problems (much less "process" or fix them) is a huge, huge imposition. And I don't think I can adequately express what a huge relief it is for me to have not only vanquished my past drama llamas but to know how to neatly send any new ones packing.
