What’s the best thing to do?

My husband traveled for almost 2 years now living me and 2 kids behind. The agreement we had before he traveled was him going there to work to make enough money, come back so we all can leave the country. After 3 months of getting there communication became a problem. I started begging for communication and every other thing. Whenever I ask when he will be back, he becomes so dismissive and defensive. Most times shouting at me for asking and then he stops calling and starts giving silent treatments. This has been going on for a year plus now. He is now living there without me being in agreement with him. Whenever I complain of how frustrated I am, he starts giving silent treatments. I feel exhausted, lonely and fed up. Is this enough reason to get a divorce?
