Thank you to everyone who posted a response to my initial question.
After many texts from the ex abf this morning, including abusive ones purely because I would not committ to a time when he could collect his belongings, I arrived home to find his car outside. I then text him and organised to dump his things within half an hour outside the house, then I left. The problem I now have is that I can not afford the rent on this house so I need to find a new place for myself and the girls, which he is fully aware of. Part of me, in a way is glad that i have to leave here but part of me can not believe he could basically make us homeless.
Very mixed emotions right now but I will take on board everything you have posted on here and I know day by day things can only get better. My eldest daughter believes it's for the best and both girls have given me great advice when I have self-doubt.
I have been reading many posts which give me great strength and comfort knowing I'm not going through this alone.
Thank you once again. Cyta.
