Can't get it up

Okay so me and my .boyfriend have been having great sex with no issues for as long as we've been together . Like it never gets boring with us . But tonight he couldn't get hard for some reason 🤔 & like I kinda felt like it was me .... cause we have been having alot.of relationship issues lately and barley been speaking to each other . But if like we tried everything, like it would get hard for a couple of minutes and get right back soft again . Idk can someone make any sense of this situation
