I don't even know where to begin, but all I know is that right now my head is absolutely spinning and I just cannot cope with the constant rollercoaster of emotions that I'm going through.
Broken down, split with dcs dad 8 years ago due to him cheating and leaving for Ow they were together 5 years and he left her for Ow 
and since then she has made mine and my dcs life a living hell.
They have had a baby and all I get are constant pictures of them as a family sent to me by her, whilst the last time my dc saw their dad was 3 months ago. She knows that he wasn't really around when they were their babies age and it's like she wants to break me or something.
I have never seen nor spoken to this woman and know absolutely about her, I have spoken to my ex who seems to be completely under her thumb and is ruled by her and by all accounts from mutual friends she is quite possessive, very insecure and jealous.
Even though she is blocked on all social platforms, she keeps making fake accounts to send to me, tonight I've had another load of pictures from bank holiday and I honestly cannot stop crying again I've messager the ex and asked if would please talk with her to stop, as it is causing me severe depression and anxiety to the point I feel like I don't want to be here anymore.
I've spoken to the police previously, but as I don't know her name or where they live I can't do anything about it. I really don't know what else to do its breaking my heart.
