Boyfriend makig his friends a priority

Hi y'all, so my bf always puts his friends before me in the sense that he spends his time for with them than me. I've brought this up to him and he said that, since he's 23 and soon to be graduated and working full time he has a limited time with his friends and forever with me... I understand his point but it really hurts me that sometimes I'm alone because he wants to be with them. It hurts that he doesn't even care that I'm home alone sometimes (I live with my parents and they're always out)  :(
