Divorce ? 🫥😪

So I have been with my spouse for 6 years now we have 2 amazing toddlers. We have had a rocky relationship but we had just decided on going to therapy to see if that would help. I went out of town for a family matter but one week turned to three weeks. He would call me and call me sometimes I would answer sometimes I would not again went to see a close family member that was sick (grandmother ) we are from the same town so his family got upset because we did it stay there. When we went to visit they treated us weird again my spouse did not go with us on this trip because he still in process to adjust his status in the United States. Then his brother left to the us with wife and everything changed he started to become distant and not call us and say we had something better to do. A few days a passed and he’s attitude completely changed . I was confused but thought maybe we will talk once I get home. Thankfully grandma recovered and was finally back to normal so his mom invited us to stay over for last 3 days at her house with the kids. On the 2nd day she kicks us out and she sent someone to tell us this and my mom in the us calls me to tell me that my souse said that we are done and told everyone else and didn’t even bother to tell me or call me he dropped off the car and keys and goes to our apartment complex and pays off to move out early and puts all of our belongings in storage and takes the keys and it has now been 5 days and won’t call me or nothing I have been trying to contact him because I need stuff for the kids and now I have to figure out where to live with my kids and look for a job. And even if the kids want to speak to him he won’t answer it breaks my heart for my babies Because they cry for him. This such an odd behavior and now I’m thinking about just filing a divorce but I’m so confused and need advice
