Make sure you are ready to move in with your boyfriend. Be honest with yourself before you bring it up with him. "Cosmopolitan" recommends you consider how much time you spend with each other (including overnight stays at each other's places), how he makes you feel, how he treats your children if you have any, and what you have discussed about your future together. If you have any doubts about the relationship, now is the time to address them, before you start living together.

Make some hints about living together to see how he responds. Mention that you would love it if you could spend more time with him. Leave more of your belongings at his place and see how he reacts. Tell him the lease on your apartment is about to come to an end and you're not sure where to move next. Talk about friends who live together, focusing on the positive aspects of cohabitation.

Ask him if he would like to live with you. If you have no concerns about it yourself and he has reacted positively to your hints, it's time to take the plunge. Choose an appropriate time to start the conversation, when he's relaxed and happy and things are going well between the two of you. Be prepared for him to say that he's not ready; at least you will know for sure how he feels and you can decide what to do from there. Get excited about your future if he says he would like to live with you and then start taking steps to make it happen.
