Well I have a few thoughts.

First of all 2 months is an awfully short period of time for you to be expecting a fuller commitment. You need to give this relationship a lot more time before you can have such expectations.

It seems to me that you have way more time on your hands than he does. Are you jealous perhaps he doesn't have more time to give you? Have you considered this? Perhaps you should.

It sounds like he is way over stretched in his life. You need to respect that. At only two months into the relationship it is far too early to be inserting yourself into his busy life and routine.

When it comes to communication you and he need to have a chat and come to an agreement about expectations and boundaries. It is unfair to expect that he stop what he is doing to be at your beck and call. For example, if texting were to be your preferred mode of communication set a standard regarding time frame for responding. Perhaps texting - and even calling - should be confined to only a certain time of day excluding emergencies.I know it would never occur to me to text my boyfriend while he is at work unless there was an emergency.
