Dh and I have only been married for 2 yrs 4 mths and have an almost 2 year old son. Our relationship has never exactly been some big romance movie type thing but he's a nice, dependable man and we laugh a lot together and I see him as my best friend.
The thing is lately it has got to the point where we hardly every kiss, and when we do it's usually just a peck on the lips. I want to have more kissing, but to be honest I find myself grimacing when we have a snog 
and even when we have sex there is hardly any kissing. I don't enjoy sex very much (not that I have told him) but feel a bit saddened when he doesn't want it either- I realise this is unfair of me! He rarely does anything spontanious for me anymore and the affection is fading. I feel that the spark is fading and I realise that this happens in most relationships eventually.
What worries me most though, is that I am starting to feel that perhaps we are too different to be a good couple. We don't have very many shared interests anymore as I feel I may have changed since we first got together. (for instance, I love literature- he has never read a book from start to finish!)I also worry that we might not have the same values in our lives. I'm worrying I may have married the wrong man.Please tell me if you think I can fix this? I do love him and care for him, and don't want to throw away our family life but I feel unhappy.
