Oh this is so confusing it is just one thing after another.

 I was not married but lived together as a couple for 10 years owned property together 8 years and have a 4 year old son.  She left me for someone else.

I aggreed to pay my ex 50% of the equity from our house and it is up for sale at the moment. Due to the current market I am sure it is going to take a long while before we get an offer and I am sure we wont get anywhere near the asking price.

Well if we were to get the asking price then we would both come away with £18-£20k. I have placed an intial of £16k which she has flatly turned down.

At the end of the day there is no law when it comes to 'common in law' couples. I have said to her if it is a case of the money then she can have every penny from the sale if I have custody of our child. She was not pleased with this suggestion and said what sort of person do you think I am?

I paid every household bill and mortgage payment for the past 8 years her money was used for food she only works week ends and get about £80 per week.

 Not sure what to do now I can not really afford to offer any more as would not be able to manage the repayments.

The other option is for us to keep the house as it is with just me living there, I could then rent a double room and give the rent money direct to the ex. We could then keep the property as a joint investment.
