Too early to talk about marriage?

So I’m with this man and he’s super sweet and he loves me and he makes me feel comfortable in my skin. He protects me from my brain when I start remembering all the abuse I went through with my ex, he assures me that he loves me and I’m amazing and perfect and he’s slowly helping me love myself.

Recently he’s been telling me he wants me to be his forever and we’ve started talking about marriage. I’m the weird ocd kind of person who likes to plan everything way in advance so when I told him I’ve wanted to start planning that just for fun, he told me to go for it and plan everything out. I managed to plan my entire wedding yesterday and today all except actually booking everything (because that takes money and commitment and we aren’t even engaged yet, it was just for fun) and it’s really got me thinking.

It’s not like we’ve been together a long time or anything, but I just feel like this feels right and I can really see myself marrying him. My question is: am I crazy for thinking about marriage so soon? Am I moving too fast?

Edit: we haven’t been together very long at all, only a few weeks, sorry for not being specific before😬
