I am having doubts about my long term relationship of 5.5 years. I'm not sure if it's normal to have some niggling doubts or if it spells the end. Our relationship isn't necessarily bad but I've wanted to get married for a while and he keeps making excuses to put it off and I generally feel undervalued. I love him and he is my best friend but I'm worried that I'm going to look back with regrets and wondering if he's really in it if he hasn't proposed after almost 6 years. I think he has it quite good as I do all the cleaning and day to day running of the house and contribute a lot financially but I still feel like I'm not really good enough. If you're in a happy relationship, have you ever had doubts and eventually got over them?
