Boyfriend knows he has an anger problem but...

...He doesn’t want help. The problem is, he took social work in college so he knows all of their “tricks”. He won’t be able to take a therapist seriously. I don’t know what else to offer him. He was abused as a child and grew up around a lot of yelling between his now divorced parents. He lived in a woman’s shelter with his druggie mom most of his life. We have a 3 month old boy and he is super sweet and loving to him. However, when we argue or he’s upset at something, a lot of the times he swears and yells at me in front of him and I don’t want the behaviour to continue. He doesn’t know how to control himself. He always feels terrible and cries after his random outbursts. He is 24 and We’ve been dating for 4 years. No, I am not being abused by him. He’s a very sweet and caring boyfriend he just needs a little help. Thanks everyone!
