I’ve been considering it for a while. She was my neighbor, long-time good friend, and I’ve been into her for a while. We started going on dates and becoming official not too long ago, and I was thinking of moving in with her.
All our families completely support the idea and so does my GF.
I wish you all the best, but make a plan of what you are going to do in case it doesn’t work out.
If you broke up could you afford the rent on your own? What about in a few years time? Consider how much rent will increase in your area.
Do you have somewhere else to go back to, family etc?
Edit: to answer the post title, my opinion is wait until you’ve been together at least 1 year, or whenever you think the “honeymoon phase” is over.
