I ( female 22) am in relationship with my bf (male 25) for 3 and a half years. We had our fair share of fights but we always worked it out. Recently he became a bit cold towards me He started not responding, he doesn't even text me anymore like he used to. He went on a business trip and we haven't been communicating since. When i try to ask why he shuts me off or doesn't even respond. He shares story's, post's and all,but he doesn't want to communicate with me. Should I be worried and WIBTAH if I break up with him over this..

I may be paranoid but i really don't want to lose him..
