I only come when I think about my cuddly toy. My girlfriend thinks it’s weird and is almost jealous of this toy. She wants me to think of her. But how can I change this?

Accept that you need to think about your cuddly toy in order to come. Don’t talk about it with your girlfriend anymore. It’s completely normal if before orgasm you block out your lover and concentrate on your own thoughts or feelings. This is the solo phase of sex. The way people concentrate differs greatly. Some focus on the feelings in their genitals, others see a certain colour in their mind’s eye. But many have a picture or scene in their head. You obviously concentrate by thinking about your cuddly toy. There is nothing wrong with that. But if you really want to change it, start experimenting when you are alone. When you masturbate and are ready to climax picture not only your cuddly toy, but picture your cuddly toy in the arms of your lover. If this works, make the toy smaller. In the end you only see her and no longer the toy. But it hardly seems worth the effort. Show your girlfriend in other ways you appreciate and love her. For if she is jealous of your cuddly toy she obviously feels insecure.
