Am I making a big deal out of this?

we've only been together for a month and an half. He doesn't usually does this but often he told me he'll call me back later but doesn't. Like today we were on the phone and he was getting a call. He answered then continued on talking to me but said he had to finish his work and he'll get back to me. But that was hours ago. Other times he said he will call back and actually do it. A week ago he went a whole day without talking to me and I called him the next morning and he didn't answer but called back a few minutes later. I asked why hadn't he called, did he lose interest?, did he not like talking to me this and that and he told me he had just been tired and busy that he even was falling asleep on the job. He continued to keep me updated after I explained my concern. Then the next day he called and was talking about wanting sex most of the day. He works two job and has always worked two jobs but the communication didn't start slacking until now. am I making a big deal outta this?
