Anxiety about my relationship and engagement

I'm having a blah day and need someone to talk me out of it. My best friend has been off the grid for awhile so it's hard not having her to talk to. I just feel anxious about my recent engagement. We are talking about putting my name on the house and all of that good stuff. I was fine with it when we talked about it. Now I just feel super anxious. Like, are we moving too fast? Is it a good idea to partially combine finances before we are married? I'm sure I'm being stupid. I'm just having a down moment. Ugh. Okay, rant over.
