I think you should talk to him about it. Ask him why he's doing things and acting like that. Is he under stress or worried? Ask him how he feels and if he wants to continue the relationship or not. And if he doesn't, move on. No use staying with someone who doesn't love you back. If he does, work with him on how to fix it and make it so you're both happy.

Figure out what's going on in his mind and in his world because change is due to circumstances sometimes. More importantly, you need to express your concerns. Tell him what you have noticed in him that has been different. Tell him how you feel. Pride will kill you in any relationship, so tell him how it really makes you feel deep down inside. And if he cares about you, the way he needs to in order to keep up this relationship, he'll get it together. If he needs help, help him with whatever it is. This can be pivotal point in your relationship. Its time to pull out everything. But just remember, it has to be mutual. You cant do it alone.
