Couples start knowing each other on a closer level when they live together, which prepares them for a married lifestyle. I have never considered living together as a test, but in reality, it is. There are couples who move in together and realized that their relationship has not future. Some might even question if their partner is even marriage material. If your both sure that you want to spend the rest of your life together, living together can be a good start of your life together. Your guy might now have the perfect ring for a proposal yet and you may not have enough money to plan a wedding right now, but at least you know for sure that you want to start a life together. Additionally, moving in together right after the wedding can be quite stressful and planning a wedding is enough work in the first place.
