Dating someone for 2 months

Hi all, I’ve been dating a girl for a couple months mow, we get on really well and defo have a really good connection. I can see a future with her, she isn’t ready for a relationship yet but says she can see a future with me.

With my autism I tend to get ahead of myself and plan ahead.

What’s the best way to combat this so I can enjoy the moment and when the future stuff happens when it happens?
