Why not both? You could be both depressed and don't like your partner.

Though depression could just as well be a side effect of not liking your partner: that is not wrong: it's a normal reaction when you don't move on. Treat depression as a signal to "move on".

In general when a person asks a question like this they have already made their mind and are just looking for external validation: for someone to say "find someone else".

Find someone else.

You just have to "spam" a lot. That's perhaps the ugly truth that romatic movies don't tell you: you can't know what all is out there unless you experience many people.

You obviously don't like this relationship. Sex is more important than people think, and no amount of talking will fix you not being sexually attracted to your partner (assuming you are a guy).
