I need advice

Me & my bf have been together for a year & we have had sex like every week. But ever since like three months ago he's been coming like within 4 minutes. Our sex never lasts longer then 5 minutes lately. & its take me longer to cum so i feel like he doesn't really care about me cumming anymore...any advice. I try talking to him about it but he just apologizes but he just doesn't care i feel. & i get so frustrated & feel like I'm wasting my time having sex at all cause i feel used all the time 😕
