denies adultry on his rely to petition

Just received letter from my solicitor with a copy of husbands reply to court prtition. no surprises here as he denies adultry. my solicitor has his lovers address, name, dates when he visited the country she lives in. He does not deny the affair to me face to face, in fact brags about it, its still on going if he could leave to go to the country she lves in. but he wont go yet until he receives his share of assets. So he has told me he is only denying adutry so he does not have to pay my court costs, however he is not defending the divorce. I dont quite understand how on his reply he can deny the adultry and then state on the same document not defending divorce . what does this mean?
ANy help received with thanks

He is happy to get a divorce but does not admit adultery.
Court costs are relatively small. I would not get wound up about this - I certainly wouldnt waste any time trying to "prove" it. Waste of your time, money and emotional energy

my x didnt agree to what petition said but agreed to the divorce going ahead.court costs,I paid my half of the court fee as he refused to pay mine.my half was £170,so I just paid it.

I agree with the previous posts. Unless it is admitted via the court Adultry is difficult and expensive to prove. I'd pay the court fees and use Unreasonable Behaviour. Do you have agreement on the financial settlement?

You can deny the charges against you but accept the divorce. Thats what I did. My UB reasons were made up. I wrote them for her. So I denied the charges but accpted the divorce. Job done. If he has returned the service and has not ticked the box to defend then thats that. You will be granted your divorce. You dont have to name the other party in adultary but if you do they will be serviced. Chris

He wont agree , settlement, all he wants is money, ie sell the house he wants half, however he has other assets in his name which he thinks does not have to half, thats why i am using solicitor
