Op so you and your dh love each other , but are not "in love" with each other ?
Did i read that right ?
A baby isnt what you need. Babies cause stress and grumpy , sleep deprevied people are not the easiest to get along with .
I think you would be better to have a nice "child free" holiday !!! . No kids ,so you and your dh can have some fun with each other . If you can get each other to laugh ,then then spark/lust might come back.
I know it sounds a bit daft , but if you give your dh a small compliment now and again ...and casually mention things you did in the past that you both had fun doing it might help him pay you a bit more attention.
I think doing something adrenaline rushy would be quite good.
Thing is to Have Fun with your DH ... once you get the " im fabulous and amusing and great company " thing going on , your DH will enjoy himself more and see you not just as a wife and mother , but his sexy best friend who he is lucky enough to be with. The romanitic side of things will catch up , without you realising !!!
If your still broody after getting you and DH out of this phase , then you would be in a better place to discuss more children.
