How to know if your boyfriend is serious about you
Notice how often he says " we.
" pay attention to how often you hear him say " we " in reference to the two of you. A man who is serious about his partner will think of himself as being a part of a couple.
He will tend to reference you and the relationship often and will make plans with you in mind. Notice especially how often he does this when you are not a part of the conversation, such as when he is on the phone with his friends.
