Hi Moshy1,
I am new on here, looking for advice but what i know currently as being in a similar situation is Call Citizen Advice i had meeting before lockdown and it helped me greatly. He look all my finances and bills and showed me i could live as a single parent. I haven’t yet but i know you can get 1/2 hour solicitor (family law) free, best to have your questions ready beforehand. I don’t think you can be forced to sell the house as your children/child is living there. But that’s when it can start getting expensive with solicitor fee’s.
It sounds really awful what you are going through and to have to process the emotional side and heartbreak whilst separating. I have/had been with my Husband for 20 years and i have gone through a grieving process for me and then for the heartache this will cause our two children. I feel other than our beautiful children i have nothing.
But i really feel Citizen’s advice is the first step, they have loads of advice pages as well online. I wish you all the best, stay strong you can do this.
Also if getting stressed i find some relaxation audio, i use Paul Mckenna deep relaxation and Louise Hay’s I can do it (cd & book) really help me. This may not be your thing but really helps me so wanted to share.
Good Luck.
