I found all the Christmas stuff difficult so came off it for a couple of weeks.
Firstly yes you can delete ex...He is your ex for a reason.
You can hide anyone's post you particualry don't want to see...Or also delete..
why don't you stop clicking on it see how you feel.
I also think you need to understand FB is not real life.. Most don't write DH is sat on sofa snoring is his pants.
Done nothing today couldn't be bothered.
Parents evenings are often not as they are.. The mum from our school who shouts the loudest about how proud she is of her DS at parents evening is the mum of the child my DS comes home and tells me is always in trouble..
It is not a reflection of real life...
However I find skimming through the same as reading MN, sometmes interesting sometimes not, sometimes I comment sometimes not.. My RL friends not acquaintances know what is going on in my life not those on FB.
If it is not making you happy though change it
