how to reconnect in a relationship

my boyfriend and i have been together for three years and for the first time we’ve had a discussion about whether or not we’re going to stay together. he said he’s been feeling disconnected and he’s felt it for months and i’ve kind of felt it before to and i’ve mentioned it before but i feel like i worded it different, so i’ve said i’ve felt like we haven’t really been on the same page lately and he said he understood. he said he’s been feeling this way for a while, he didn’t really say how long, and he doesn’t know what to do because we love each other and we don’t want to break up but he just feels like he’s not sure what to do to feel that connection again and during this discussion i saw him cry for the first time ever in my life. we decided we weren’t going to take a break or anything, we’d carry on like normal and more so him than me would just take some time to see where we are and if we want to stay together. i really don’t want to break up, i love him so much. and it doesn’t feel like anything’s even wrong, no one cheated on anyone, we still talk like we used to, no ones really neglecting anyone else, so i don’t know what happened. any advice on reconnecting and getting through rough patches is very appreciated, i just feel like i still love him and i know he loves me and there’s nothing wrong with us as a couple to break up, but it’s a very sad and confusing feeling, i haven’t even been crying i’ve been shaking and having what i think might be panic attacks, i’ve been breathing different, and ever since we had this conversation i’ve felt like i’m going to throw up.
