If you have even a faint thought that you might settle if you continue to date this guy, then you know that it's time to leave him behind and find someone who you don't feel like you will be settling with. It's easy to tell yourself that it doesn't matter because it's only been six months and you're not ready to live together yet. Follow the below exercise.
This is when you find out if you two really get along, if you like each other more than you simply like being able to say that you have a boyfriend or girlfriend, and if you're compatible in the long run. You should be with someone who knows much sooner that you're the one for him. Otherwise, he would love to talk about living together. Lack of commitment quickly becomes a control issue in relationships. The fact that you two have gone on at least one trip during this time frame proves that your love is going to continue to grow and things will work out. Be clear with yourself on how long you intend to wait and what it is that you are waiting for — the man or the idea of what the man can be?
