Re: I really need advice.
Have you heard of marriages having ups and downs? Sounds like this is the down time in your marriage. I think every couple deals with it differently - some, like you, try to work harder, find a spark (putting sexy clothes on), some just wait until it's over, not doing anything special. It does feel like a very lonely time.
Some people would advise you to keep working on it, but I personally wouldn't do anything and see where it would go. I wouldn't probably allow "chatting" with female friends, though, but that's me. Most couples do cool off in bed with time, so that's normal.
The most important thing is, are you secure in this relationship? There is a lot of your own feelings and temptations, and it's confusing. Just wait and let it all settle down.
