nonstop arguing

My boyfriend recently moved away to go to college, since then we haven't stopped arguing. We argue about almost everything. I love him with all my heart and I don't know what to do. I'm very anxious about the things he does all though o do trust him. He's been saying things that are kinda mean.. Like small digs at me during the argument like saying that the arguments are my fault because I get mad at everything he does which I think is intrue.. I get frustrated when he goes out and doesn't talk to me at all or doesn't communicate what he's doing.. I just want to be updated. I also feel like the friends he's made have changed hi.. He's a very sweet boy and I feel likehes turning   Into a bro. Does anyone have any tips on how we can stop fighting or resolve them? Thanks for reading :)
