As someone who moved in with her boyfriend, I really really don't recommend moving in before marriage! If things go south, it's very hard to break up and move on. Being around the same person every day, 24/7 can also ruin your relationship. I don't mean to scare you, but I would wait until marriage.
It depends on what you want from the relationship. If you want to get married but he doesn't, living together isn't going to move him towards wanting to take that step. But if marriage isn't in your plans (or at least not with him), move in together and enjoy yourselves until you are ready to look for "The One".
Until you both decide you its time to marry each other and have kids. Wait as long as you can. And if you do move in with him, don't put his name on anything of yours! Keep your own bank account, own credit cards. Own everything.
take your time. I miss missing my partner. Although at first moving in together is everything you hoped it would be after a while you just miss the way they treated you before. its hard to always be at your best for someone. Let him be your super hero and take your time!
