my husband and I have been together for 5 years and married for two. now in my opinion the man I married was sweet and easy going, lately he's been irritable, and snappy....our sex life or lack there of is rocky, now i know it's a two way street and i'm not perfect, I have my day's to, but at least I admit it, if I bring his attitude to his attention he says that it's not true and has no idea what i'm talking about, we are both very busy since we both work but we are both home by 6:00pm we have three daughters so by the end of the night we are both exhausted, not sure if that's the reason why, but what i'm trying to avoid is us getting to the point where we get used to doing things on our own, such as being in seperate rooms or just avoid each other because we both end up arguing, how can I get the spark back?
