So many relationship issues can be resolved with just a little reading between the lines of separation...then actually doing something about it! As couples progress in life with buying a bigger home they tend to start drawing a line between her stuff and his stuff because they finally have the space to do so. The builders don't help with this either as they designate his and her sinks, closets and even garages! Then there is the furniture with his and her recliners and the ultimate culprit, the king size mattress with the 2 separate twin size box springs.
As each year passes and the couple keeps adding space between them (and their stuff) then the couple will eventually separate from their commitment to each other. Couples are considered as One and should keep their stuff together and not separated. Not to squelch anyone's independence but when you start thinking and doing things independent of your partner, then the best interest of the couple no longer exists and the bond between the couple dissolves.
Remove the space between you and your partner. Mix your clothes together in the same closet. Mix items at each sink - both toothbrushes should be at one sink. Start with these simple things and you will rekindle your early years of when you first met and could not get enough of each other!
