Taking a break from my bf of 3 years...

For a week now, my bf & I of 3 years have not had sex. This is completely fine (even though I was worried) because it's happened before. We go through "dry spells" where we won't do it for a week, sometimes 2. Even though I was worried, my bf reassured me endlessly, saying it'll come back & that he loves me.

Last night, I came back from work to him & I knew something was wrong right away. I kept asking him but he said nothing. Finally 5 mins later he told me that he isn't sure about me anymore, & that he's been trying for about a month to get "back in love with me". We've been through something like this where he's told me he feels like he's falling out of love, but we talked about it & figured it out & it was okay. I don't believe that his love for me could've vanished that quickly within a month. And also I can tell when he's trying, & I know he wasn't trying with every action he did. I knew he loved me endlessly & it just doesn't make sense.

It got too into the night last night so I had no where else to go but sleep over at his house, even though he said he doesn't want to do this. We slept in the same bed but he didn't want to get close to me at all because he was still going with what he said.

This morning we woke up at 7 am & we talked more. We decided it's best to take a break. We both set boundaries (no seeing or talking to anybody...act like we're still together) & a time limit (2 weeks). Before or at 2 weeks we'll get together & he'll tell me how he feels, either good or bad. I decided to leave most of my stuff at his house because I feel so strongly that we're meant to be. I just don't know what to do...this hit me out of no where & I didn't expect it. We decided that we'll only talk to each other if we desperately need to, but that's it. It's only been 3 hours since I said bye, & I don't know what to do. I'm terrified & scared, & haven't eaten as much as I should. What do I do?
