Financial Worries

Hi
This is my first post but have been reading all the posts over the last few weeks. In a nutshell, my husband and I separated 7 weeks ago after I found out he had continued an affair he started 10 months ago. Its all a bit of a nightmare as 3 times I found out he was still seeing the OW and foolishly took him back. Anyway, he is now living with the other woman and her 2 kids in rented accommodation.
I saw a solicitor 2 weeks ago and came away thinking the financial split suggested by the solicitor was too generous on my part. I have arranged to see another solicitor for further advice next week but wondered whether you could give me some advice.

Married 16 years
Two children - 13 and 5
My salary - £36k + non-guaranteed annual bonus
(my take home pay £1,900 due to paying £200 per month annual season ticket)
His salary - £26k (his take home pay £1,600-1,800 including "mileage") + additional income between £100-200 per month

My ISA £10K
His ISA £8k (upgraded car prior to separating!)
Me - Additional £4k but need to fund spending money on holiday

House - Mortgage £47k, Equity approx £150k
We both work full time, both have pensions (dont have CETVs yet although his is local govt final salary but have a feeling mine may be worth more)

As I said, he is living with the OW, she works full time too so there are two salaries available there. I am PWC and he has made no arrangements to see the children at weekends yet. I am finding it hard to carry on on a daily basis with the stress of the financial side of things. I have always paid alsmot twice as much as he did on household expenditure (i.e. mortgage, utilities, childcare) and am expected to carry on doing so. Solicitor mentioned going for a Clean Break and this would be ideal as I dont want to be tied to him for 13 years with a mesher. With a mesher is the % agreed at value of the house now or in 13 years time? Question is, how much might I be expected to pay him? On paper my salary is good although with outgoings I know I will be struggling to find £75k if its a 50/50 spit.
Will the fact that he is cohabiting, the fact that she is earning, and the fact that I will have to maintain home be taken into consideration? Am so annoyed that he can play around and I am left to pick up the pieces.

Hi Debs
You probably need to list the pension CETV as well but if you have care of your child I dont think it will be a 50:50 break.

Have you tried the divorce calcualtor? Apart from maintenance etc mine worked out spot on at 60:40 which has now been agreed....not signed yet but fingers crossed.

Others here will know better than me.

Take care
