My husband spends all his time on phone and watching tv

Hello everyone, hope you all keeping safe .

My husband of 5 years doesn’t spend any time with me and our kids who are 4 and 2 years old .

Today he was sitting on the sofa watching videos on Facebook. My 4 year old threw a small toy which hit my husband. My husband became very angry and got up to slap our daughter . I tried to stop him and he manage to hit her on her head . When I told him that he wouldn’t have done that he hit me and pushed me front my kids and my mum ! He was also very loud and abusive !

I love him but I have finally found the courage to let him go .

Please be honest who’s in the wrong ! And advise me. Thanks in advance
