Set a date to just go out have have fun. Goto the Cinema, or on a bike ride or out to lunch or something. Just get out of the house, and get away from the fight.

Say 'sorry'.

tell her you are sorry, and be sure to include why you said those things and what was bothering you. If you don't fix the initial problem it is bound to happen again.

She's your mum and she loves you unconditionally. Your mum is the only person in the world who will not hold anything against you. You are still best friend's but she may think you haven't calmed down yet and so she is keeping a low profile. I don't know what your relationship with your mum is but there are several thing's you can do. You don't have to say anything but just give her a hug, or you can just break the ice by asking if she would like a cup of tea or coffee or maybe just leave a little note saying sorry or love you mum. You always hurt the one you love as the saying goes and it is a very true saying. What ever the arguement it will all be forgotten and thing's will be back to normal soon; until the next time. Good luck.

Ok - you don't say why you fell out or how things were left - did you resolve it or was it one of those silly arguments that you aren't sure what you were arguing about but neither of you back down so it just hangs around like a bad smell. If you were in the wrong say sorry - with a hug or a note or whatever you feel comfortable with. However if it was not resolved or you feel that although you upset mum it was a difference of opinion and neither of you are right you should agree to disagree and not talk about it again until you can both accept that there are some things that you will have different opinions on. You don't say how old you are but I can tell you as a mother that there comes a day when you realise that your kids are growing up and forming their own opinions and nobody trains as parents for that day. Maybe mum wasn't ready for an adult argument with you and she has been quiet because she is processing how she feels about it. As was said above Mother Love is unconditional and she won't hold it against you. Talk to her she's the best friend you'll ever have and she needs to know that you are feeling bad cause you two fought. Good luck
