I'm coming up to the 23rd year of marriage. Each year it seems to be getting harder to keep the marriage going. I don't know if it is to do with getting older or what. We have two lovely children aged 20 and 17. DH has a 85 year old mum who still thinks no woman is ever good enough for her son. And there's a SIL who is goody-goody two shoes and I feel DH benchmarks me against her. I don't have my family here - they live 10,000 mile away. It does feel lonely sometimes. Anyone who's still in a long marriage has any tips for me?
