Relationship over - how do i tell the children?

[Pricklepants77]

Help I could really do with some good advice! I am divorced mother of 3 . I have been in a relationship for 2 years with a good guy - but these things are always a long story and it had become apparent that we are not right for each other and have decided to end the relationship - amicably .
My two youngest (14 and 10) really love him and think the world of him . We never moved in together so exdp is fun and they adore him .
I just don't know how to tell them . They are old enough to understand but I really want to handle this well - they have been through the breakdown of my marriage and exh subsequent tumultuous love life since and I really want to not leave them destabilised by this , can anyone help me ? Xx

You tell them relationships break down. They come to a natural end and people are sad but move on.
Nothing you say is wrong unless you do blame etc?

Thank you for replying.. I am just going to be so sad that something I have done will cause them distress and is there anyway I can mitigate that ? When my marriage broke down I knew it was the right thing and that we were going to be OK amd even though it was 4 years ago i also sensed they knew it was the right thing for us as a family but this will come out of the blue for them .
