It's so hard isn't it?? I had to read this post to my husband so he knows we're not alone in these thoughts..... lol.
Here are some things that work for us:
Sleeping in - One person gets to sleep in Saturday mornings and the other gets Sunday mornings until 8:30. It's enough to look forward to..... but not too long.
Working out - Justin really missed working out after work. So he is "allowed" (for lack of a better word) to do whatever as long as he's home by 6:30 so he can see Ryan before bed which is at 7.
Happy Hours, etc. - We definitely split up this time. I go to a girls dinner every week or 2 and usually we will meet up at 6:30 or 7 so he is basically just having to put Ryan to bed. You really have to give and take on this one!
Mornings and Evenings - we take turns cooking. Sometimes I would rather cook by myself than build one more block tower, (lol) and it gives Justin a chance to play with Ryan since they haven't seen each other all day. I don't really like breakfast foods so Justin doesn't mind getting in there and making bacon and eggs some mornings. Even if he's just sitting there while Ryan eats yogurt by himself, it gives me a chance to take a quick shower in peace and get ready for the day.
We do dates too.... my in-laws live close by so they will watch him for us several times a month. That gives us a chance to see a movie, or go to poker night, etc. Taking turns is nice but sometimes you want to do stuff together too!
On weekends we try to do something fun together, look in local publications for fun activities in your area.
Hope this helps! I'll be watching for more suggestions. :o)
