Hi Layla
I haven't been to Relate myself, although friends have, and I found out a bit about them years ago, whilst doing a counselling course. Incidentally, it is a general rule that counselling tends to make things feel worse, as it is bringing things out into the open, so that they can be dealt with. I know that that is really hard, and I do feel for you, trying to carry on a 'normal' family life at the same time. I'm not sure that I could be that brave - I like things to get fixed, now, and for them not to drag on. But life ain't like that and it could be worth it in the end, as long as you are both being honest, and as long as you both want the relationship to work.
Perhaps having separate rooms, and some space in your life can give you a break from 'constantly trying to please him'. That sounds very very tiring - and is an impossibility, of course. Have you negotiated space in the week for you when he does the childcare? Evenings off to take a long bath, read a cheerful book, or go out with a girlfriend and laugh, if you can?
Christmas is going to be tricky isn't it? Have you told your family about the problems you are having? If not, could you say to your parents that you would like a change this year, and could you come to them? If they are happy to have you then it will give you a break, and you can concentrate on what is going on now for you, without having to plan for what ifs?
