If he is not considering it does he really love you then. I don't want to judge because I don't know your dynamics, but a relationship works with two people involved in it, you need to consider your steps I guess. And If you still feel he loves you you need to have a talk with him i think
Just give it some time. I know you are feeling lonely but time mends everything. You should ask him the reason why is he not paying enough attention and ia there something that is troubling him. Wait for sometime, if then also nothing happens you should move out of the relationship as you've already told him about how you feel and if still he doesn't considers it,then there is nothing that can be done.
Just have a conversation with him like a friend and forget you're in a relationship for that time. Expectations are so high when you're together, just open up yourself to him and try to accept his point of view and work towards a solution and not blaming each other!
