I need advice about my boyfriend ?

Are you sure he's your bf? He's acting as if he could care less about you right now, yeah i get that he's busy with school/exams/family etc but if he really cared about you he would FIND the time to see you. If he truly was your bf, he would FIND some way to talk to you on the phone or text you even if it's just a one minute break. If you're not able to text him and talk about yourself for fear that he won't reply, then he's not a good bf. You deserve so much better than this. If he's not willing to make some sacrifices to be with you, you should just leave him. He is probably feeling comfortable about your relationship to the point where his mentality is "oh she'll never leave me" and he treats you badly. don't let this happen to you. If it doesn't feel right and he's not willing to make an effort, it's time to end things.
