Hello Elle gross, and a warm welcome to the site.
I can understand that a serious relationship may not start until the end of the year, however, if I loved someone I would still be in contact with them on a daily basis so that no one else could attract you away from me.
No matter how engrossed someone is with their studies, having and talking to a close companion they eventually want to date is a way to distract your mind off the study and beneficial for your health.
If he is talking with other friends it's not a reasonable request why he shouldn't be doing the same to you, unless these friends are who he plays sport with.
When this isn't the situation, what do you do when you have a problem and need to discuss the outcomes, there may be nobody which can affect your own studies and the relationships you are trying to be part of, which is a concern for you.
You can't turn love on and off, it's too strong, and if he doesn't want to talk with you, then someone else may come along and take your heart.
You can also ring Kids Helpline 1800 55 1800 and talk with them, webchat or online but really hope you can get back to us.
