Just need to vent

I’m getting sick of my husband’s anger issues. I’m sick of how every little thing upsets him. The dog starts to bark, he gets anger. When he cooks and it doesn’t go right, he’s angry. It’s starting to drain me. I feel like no matter what I do, he’s just going to get angry. I just expect it now when something happens. He’s going to therapy, but he has only gone to three sessions and I’m starting to think he’s not going anymore. I told him if he stooped going and he didn’t get better with his anger I would leave him. I just can’t do it anymore. Im stating to not love him anymore. He’s no longer my husband, he’s just a roommate that I no longer want to be intimate with. We have a one year old son and I don’t want him to end up being angry like him. My husband is not abusive and has not hurt my son nor I. He’s great dad. He plays with him, he cooks, cleans, he’s handy, but his anger is to much for me to take. I guess I got to start planning on leaving him. I should also add that he has tired to message people in our area on Reddit about hooking up or when he’s away for work for two days. Multiple times. I think I’m just done. It’s not worth saving and I’m not going to let my son grow up around it.
