It's hard word sometimes, but by making a determined effort not to forget about watshisname. 
We live away from family/babysitters, so nights out aren't possible, but we have 'days out' when she's at school. It may only be a coffee out or a walk in the park but it's time when it's just us.
When the weather's bad we listen to 'our music' and sing along no dancing yet
It was difficult especially when DD was very small, I know I didn't pay him much attention, but the romance has come back, he still makes me laugh.
Also, she has a reasonable bed time, so we get grown up time in the evening.
