Like 2 months ago my mom found out that my dad was cheating on her for almost a year and that made her change the way she is, even thou my dad apologized, broke with the other woman and has been trying his best to gain her trust back and has even been going to couple therapy with her I feel like she takes 1 step to the front and 2 steps to the back cause she can be happy all day and out of nowhere for no reason she starts arguing with him and even hitting him, I know she needs to see a psychiatrist but she doesn't wanna go so I don't know how to deal with this.
