<human>: We've been dating for almost two years, and living together for about a year and a half. We'd been friends before we started dating, and at the time, living together was the only way we could be together. (Either 3k miles between us or no space at all)

He says that he's sure he loves me and wants to be with me when we're lying in bed and cuddling or doing other...stuff (wink wink), we can lie there and just talk about life, even the condition of our relationship, which is clearly very bad right now, and he still knows he wants to be with me. He said that he feels a little better about it when we do something like go grocery shopping, too.

But when morning comes and I have to take him to work, or yesterday when he asked me to drive him to his interview, he starts to feel unsure if our relationship is a good idea again. It's been like this for almost a week now.

I'm going to stay with my family for a couple weeks soon, I think I'll leave next Wednesday, hopefully putting some distance between us will help... This situation has me really stressed out and sad, I can't eat, my chest is constantly tight, I'm sad unless I'm home with him and we're lying in bed together...

What could be making him feel like this? Could he just be overwhelmed by my constant presence or is it something more serious like he's falling out of love with me?

Can you give me the gist of the text in a nutshell?
<bot>: Live with BF. Work with BF. Hang out with BF. We're always together. Sometimes he loves me. Sometimes he's not sure it's gonna work out. What do?
