what does it mean when he says he doesn't want to break up but he is not sure if he loves you anymore?

Everyone goes through times when they question themselves and the state of their life. While it's always hard to hear, it also shows that your S.O. is able to be honest with you, despite his doubts and interrogations. Take this as some solid ground to be able to listen to them and their doubts :)

It means he is very confused and isn't sure he can handle breaking up. He might feel very dependent on you and is scared of loosing your support emotionally but at the same time isn't interested in you romantically anymore.

In this case, it seems like he can't make up his mind, but he isn't willing to commit to you. People want the best of both worlds, and have a hard time making decisions. He's breaking up with you without having the courage to go all the way. Love is a fickle thing. I'm really sorry you're going through this (it's happened to me before, and almost everyone in their lives at some point) just hang in there and you will get through it! : )

Sadly, that's not usually a good situation. If he's not sure and you need time apart, that's one thing. But not breaking up makes it sounds more like he's taking advantage of being comfortable in the situation. I had a difficult time in one relationship where a guy did this to me multiple times - it finally turned out that he was looking for someone else, but came back to me if they didn't pan out. Really painful to finally figure out and it caused me a lot of self-worth issues, but I did finally realize that someone can't just put me and my feelings "on hold" while they sort things out. True partners should want you to work through those things with them, not on the back burner.

He could be trying to express that he is looking to change some of the things about the relationship, because, for whatever reasons, he doesn't want things to end, but he doesn't feel the same way about you as he did when he was 'in love' with you. It doesn't mean the relationship is over, or even that he doesn't love you - just he is just looking for a way to open a conversation about how he feels, how things have changed, why, and what can be done about it.

Not to be harsh it sounds like he wants his cake and eat it too. He needs to get off center and make a choice. You deserve to be loved. He needs to accept the consequences

that is a very hard statement to interpret most of the time it just means that there is something that is bothering him and he thinks that he cannot make it work anymore. It is not that you did something wrong it just means he knows it deep down that for some reason like family, finances or something else he cannot keep this relation in long run. He doesn't want a break up because he loves being with u, he is used to having u by his side and he does not want to hurt u by saying he wants a break up for the most part of it. But he is not sure if he loves u or not because he does not see his future with u for some reasons that are major for him and usually in that situation people end up being just fine for a long time and the some decide to come back to knock your door while others don't.

Sometimes it means he likes your relationship but the connection isn't as strong as it used to be such as when he was in love with you

If he does not love you anymore, then that person probably just wants to be with you but not date...

It might mean that something in the relationship is missing, but the person is willing and has feelings that are worth not giving up for, so the person probably is trying to find something that is necessary for him in a relationship with someone, having hope that the love he felt will rise again.
