Will I one day move in with my girlfriend ?

For the long-term health of the relationship, please consider not moving in with her.

Here's some information from the book True Love Lasts about living together:

Question: Is living together a good choice?

 The number of unmarried couples living together has skyrocketed during the past few decades. Many of these couples think that living together isn’t a problem because “pretty much everyone is doing it.” It’s now unusual to attend a wedding of a couple who hasn’t lived together.

I’ve heard lots of reasons why people live together including, “He’s not ready to make a commitment”, “We want to be sure that we’re compatible”, “Two can live almost as cheaply as one, it’s helping us to save up for a house”, “We want to work for a few years before we get married”, “We’re going to get married eventually, we’re just not sure when”, etc.

My opinion is that living together is a bad choice - no matter how many people are doing it. Most research shows that couples who live together before marriage are more likely to:

- eventually get divorced than couples who don’t

- be unhappy in their marriage than couples who don’t

- cheat on their wife/husband than couples who don’t

If your significant other wants to live with you before marriage, it’s a sign that he or she may not be a strong person because a strong person* always tries to make a good choice, a choice that’s the best thing for the health of the relationship in the long run - and this includes the hard choice of deciding not to live together.

*A strong person has good character (honesty, integrity, trustworthiness), displays a positive attitude (cheerful, caring, friendly, forgiving, helpful, and respectful), fulfills their responsibilities (for handling pains in a positive way, for always trying to make a good choice, for taking care of themselves, for serving others), gives their best effort, and demonstrates self-control (of their body, anger, mouth and money). 

Hope this helps!

You’ve been together 3 months, relax

Don't feed the troll.

Before two people ever move in together, they discuss the important things -- finances are a big topic... how the household chores are done and maintenance will be paid for, and more. Just moving in on a whim is a huge mistake.

you'll find out later if you do

It sound like you just want to move in her house to save money. And you're moving way too fast, anyways. It's only been three months, the relationship is just getting started.
