Can the guys answer this question please?

My boyfriend bitches like a female and I am so not into that. It's like every freaking phone call we have he is bitching about something; his job, his co-workers, how tired he is, (he works two jobs, and his choice) and now its his blood pressure. Geez, am I being unsympathetic by telling him I am tired of these kind of phone calls? I mean he is starting to sound like a female. What should I do?
