DH of 7 years left on Sunday and has said he wants a divorce. He says he has fallen out of love with me and doesn't want to attempt a reconciliation - he has been talking to other women on social media/snap chat for the past 8 weeks and I suspect is having an emotional affair (I do not believe there has been a physical affair). He originally left for a week at the end of November but returned home to work things through in early December and things seemed to have improved - Sunday's leaving came as a bolt out of the blue.
We have two children (10 and 1.5) and jointly own the marital home which has around £100k of equity in after some recently building works. I am the higher earner (£56k to his £32k) and have the children 12 nights in 14 (he has every other weekend contact).
At present (this month - he only left last week) he is paying £100 pw maintenance (this is slightly more than CMA calculator but does take into account his cash in hand overtime) and £300 towards household running costs - this is equivalent to approximately 27% of our monthly mortgage payment. I am paying all other household bills and childcare (currently £850 per month).
He says he has known for over a year that he wasn't in love with me but stayed for the financial security - by this he means using my credit to purchase 2 vehicles leaving me with a loan of £10k to repay over the next two years - in hindsight this was really stupid but I had no reason to believe our marriage would break down.
He has moved back to his mother's but this can only be a temporary arrangement. He has verbally said to me that he doesn't want any money from the house/my pension - he just wants a divorce. I earn enough that I am likely to be able to transfer the mortgage into my sole name if he agrees. I could not afford to buy him out. How likely is it that he would just sign it over if I acted quickly? It would likely suit him as with an additional £300 pcm he could afford to rent somewhere adequate. It would also allow him the freedom to purchase another property in the near(er) future as I understand I could ask a court to delay the sale for some time on account of the 18 month old. In any event I couldn't afford to buy out a 30-50% share for at least 5-10 years.
I have been recommended a solicitor by a friend who recently went through a divorce and was happy with the service - she charges £70 for a fixed fee consultation and I have an appointment on Monday. Her fees thereafter are £200 per hour, £20 per letter and £20 per telephone call.
I am horrendously sad but feel I need to push forward with a divorce quickly before he changes his mind about signing it over. Advice/opinions on how likely this is to go in my favour? I'm happy to pay for an expensive solicitor if they get the job done quickly and I can keep my home for me and the children.
