Does he really care?

ok, i have been thinking lately that i need some help with this. i think about it all the time and i don't know what to think?

i like to spend time with my family, as do my boyfriend with his, so every few days we go to our families place and visit for a night or 2. it just seems when he is not with me, he has no interest. he never calls. when i do call him to say goodnight, or just to see how he is doing it's almost like he don't want to be talking to me and does what he can to get off the phone. literally, he can go 4 days without even attempting to call.

should i take this personal, it wasn't like this first going off, just the last couple months.
