I Need Advice On My Relationship

okay so, for the past few weeks, my boyfriend has seriously been making me feel unimportant. He never wants to spend time with me, but will go hang out with his friends for hours at night. he always tells me he has to get up early and hes tired with no money but can go party with whoever. i dont understand why he cant or wont do things with me but for anybody else he is all for it.
he also never wants to come in my house, ever. i dont understand what that is about. just a few minutes ago he got off work and was going to come pick me up, but when i said it would be a few minutes because im doing bank stuff online, he said he was going to go home and take a nap. why couldnt he just hang out here with me for a few minutes? it makes zero sense
maybe i am over thinking or maybe i am insecure but i am genuinely upset and he doesnt seem to care. i asked him if he was happy with me and our relationship and all he said was that he was comfortable. im not totally sure what that is supposed to mean.
im just having a really hard time and i am having trouble communicating to him
