Relationship advice

So my boyfriend and i have been together for like a year and a half. the whole first half of that time was perfect and we were together almost every day and couldn’t stand not being with each other, but recently my boyfriend got a job and he works a lot now and he only gets like 2 or 3 days off, usually the weekend. out of those 2 or 3 days he only wants to spend like 1 or 2 days with me. i’ve been upset that we don’t see each other more and he tells me he needs some of his free time for himself and for his friends and i can’t except to have all of it bc that’s not fair... and yesterday he said since i keep complaining im suffocating him.... i’m just trying to adjust and i feel like one day a week seeing each other is going to make us drift apart... i mean that’s 1 out of 7 days... any advice?
