hey - first off, well done on trying to sort things out - it's not easy when it feels like an uphill struggle.
Secondly, both me and dp are women so I may not be the most helpful person on this thread
but sometimes I think because we're both women, we're both so bloody busy doing everything all the time it's just as tricky especially to remember to be kind and make time for each other.
So, things I appreciate and I think dp appreciates - not chocolates or flowers, except for thoughtful-type chocolate - like I know she loves Star Bars so if I see one I'll buy one sometimes.
But I get trillions of brownie points if I buy her a New Statesman - she loves reading it, never buys it for herself and will then tuck herself away somewhere and read it - that's part of the present - make her a cup of tea and say go and read it!
I love having back rubs or foot rubs - waaaay better than flowers 
Recently we've started e-mailing each other from work in the mornings - just a quick hello e-mail but it's lovely. Texts every now and then also good.
Sometimes I get her bigger stuff - tickets to shows I know she wants to go and see but to be honest that sometimes causes rows about money, so I try not to 
Every now and then I'll take ds's away for the weekend somewhere - camping or to see my brother - gives her a break. And I get to go out to the pub with friends from work as I like doing that and she doesn't.
Ooh - buying a Guardian/Observer on a Saturday/Sunday is wonderful - whoever buys it the other one is instantly happy!
I don't know - it's hard sometimes when you're in a long term relationship with children - not at all easy to keep things fluffy and special, but it sounds like you're Making An Effort and that gets stilted and more difficult rather than making things easier.
I try to slow down - especially at the weekends - just slow your pace, sitting together in silence with a coffee and a biscuit is sometimes all you need.
OK, waffling now. As you were.
