I sent this:
T1000: I understand and I would like to help you, but I am not able to do so. My spending is very tight and I can't afford to pay any more than I am doing at the moment.
16:24, Wife: Did you get your Dad to write that text for you?!!! Lol

Well you can afford to go to take your lessons each week and join a gym so your spending cant be as tight as you make it out to be. A roof, food, clothing, heating, electricity and an education is what your kids need.

I should have changed the wording a it more because it didn't sound like me.
She's talking about my Martial Art lessons. I don't do it every week but nearly. I haven't joined a gym yet. She must have heard or seen something about me going to the gym on my Facebook. I went once.
She is trying to guilt me with the roof/education speech.

She is a member of a gym.
She has been decorating her house, two rooms, one of them she got a painter in to do it. Got new things for both rooms.
She is going out at the weekend which includes train fare, hotel and spending money.
I know she has had quite a few nights out recently and that includes new clothes.
She is quite often taking the kids out to eat. I wish i could afford to do that so often.

I think my reply should be if you want to discuss this we should do it over the phone or when we see each other in person.

How should I respond?
She seems to think I have to break my life down to the bare minimum to suit her needs. I want to express all the above but it will antagonize her. Do I bring them up and justify my spending?

Help!!
