My girlfriend of one month wants to move in with me but I'm not sure I want her to. She is 8 years younger, very pretty and has a good job. We have a lot of common interests with the exception of musical taste. She is an avid Taylor Swift fan and is always playing her music while I prefer classic rock.
That kinda thing can work,the Wife and I moved in together after a couple months and we've now been married for over 30 years.
On the other side of the spectrum the Wife and I and one other set of friends are the only two couples who havent had a divorce.
If it were me I'd do it,that way you'll find out real quick if y'all are compatible before things go to far.
Dont know if you own your own home or not but thats something to consider.
