Wakeup is very blunt, but she is right. He is using you. His words mean nothing, because he can't back them up with actions. Actions are how you tell a man/woman really loves you and wants to be with you. You sound pretty naive to believe his words but ignore his actions. We see this all the time. Inexperienced people believe their partner's words, and totally ignore their actions. Inexperienced people also believe "love will change him/her." Not true. If it takes a divorce for you to figure that out, then so be it. We've seen that too.
I hope you are both not on the lease, as that will make things much more complicated.
