When people post on here about relationships having problems, losing love/affection for their DP they are routinely advised to:
-work on their relationship
What does this actually mean in practice?
When I tell my OH how I feel and he will give a list of reasons why I feel that way 
If I feel isolated/alone/unloved I explain that, he says sorry and the next time I'm feeling like that he still doesn't notice and I still have to spell it out and ask for comfort/a hug.
I really don't see what I'm supposed to do to feel loved and in love. I can elicit an improved response by giving feedback, but it feels like I'm training a dog, not being part of a loving marriage.
When we communicate about our problems with the relationship/how we feel it feels like we become 'actors' for a while after, giving each other knowing looks as we remember to do something better that we discussed. It just feels like an act - I don't feel any better about him or the relationship.
