Yo guys, my dad came home and he said he will stop drinking and go to rehab. But my mom and dad aren't that happy like that they were before, they aren't fighting but they aren't talking to eachother too much...It's depressing me, tell me guys how to cheer both of them... I don't want to be angry at eachother.. When my dad come home and the next day when he was sober, they had a fight, mom yelled at dad and said stupid things to him, my dad said "yes you are right i am STUPID, RETARDED, BUT I LOVE YOU and then he started crying.. My mom was still nervous and didn't say anything.. I know u will say it is their problem, but tell me how to cheer up them pls...

Thanks.

It's great that your Dad is going to get help. I'm sorry that they're not getting along. Sometimes families go through this and then get back together.My ex-friends parents were always fighting, they broke up for a year and after experiancing other partners and a life without each other they got back together. It could be that they have to part to appreciate what they have. Don't quote me on that because i'm not saying that's what will happen with yours, I know hardly any of your situation so I can not make an appropriate judgement.
Try talking to them. Of course this is your problem as well as theirs (that sounded bad but I just wanted to use your words). If this is upsetting and unsettling you then you have the right to voice it. Sit them down and explain to them how they're making you feel. They can't know that what they're doing is hurting you unless you show them. "Cheering them up" is not your job. You shouldn't feel obliged to do that however just some small nice things every once in a while like doing the dishes or breakfast in bed can help sometimes.
I hope things get better for you soon. :)
