My boyfriend has a bad temper.

Your boyfriend is under too much pressure! And I still can't find a suitable decompression method! These are all formed over time! He cares about you! He has been nervous since you told him that your ex-boyfriend wants to get back together with you! And he can also realize his shortcomings! Why don't you take a vacation and travel? Have fun ~ talk more about what you used to be sweet and happy ... let him try to say something, don't hold it back! Communicate with each other more! I believe you will get better! I wish you happiness!
