Hi, We have twins and we had a horrible time for the first year or so. We were so exhausted and ratty. The way we behaved would have brought armies or MNers out to say LTB to both of us. I just want to say really loudly: there's probably nothing wrong with your marriage. You are both knackered. That doesn't mean your marriage is rubbish. It means you are both knackered. And no one is at their best when knackered. A marriage is in tatters if there are no external stresses and you can't connect.
Having said that, you do need to learn how to have more fun. DH and i got to breaking point and sorted out a plan we stuck to that really helped. We chunked the weekend into blocks of four hours, starting on Friday night and going through to Sunday evening. Assuming eight hours of night time (even if you get no sleep) that's nine chunks of time during the weekend.
We'd each get a chunk to do what we liked with. That meant we could each go out one night with our mates for four hours. Or we could go shopping in town without twins in tow, or we could use it to lie in and catch up on sleep, in which case the rule was that the other one made sure the babies were out of the way and didn't get to shout for us (or got taken out of the house. We'd agree who had what when and then make sure nothing got in the way of that time.
Then we'd have a chunk of time together as a couple. We'd book a sitter and go out. But never to dinner, because at dinner, we just stared glaze eyed and talked about the babies or nothing. On our night out we had to do something that was an experience we could connect over - so a gig of a band we loved, or a film, show or comedy night. Something we could discuss which wasn't DC and which reminded us of what we had in common.
Then we;d have two chunks of time together as a family. That would either be two half days or a whole day out. We'd use those to have fun together. We went to steam fairs and food markets, petting farms and beaches etc or to visit relatives.
That left two chunks of time to get stuff done: laundry, shopping, cleaning, cooking, catching up on admin etc as well as eating and showering and messing about reading the papers or watching TV. We'd also use this time to have one on one time with each twin - so one of us would take one of them to the supermarket while the other one would do some gardening with the baby 'helping'.
It really made a difference to us.It was simple to stick to. We both got a break for half a day or a full evening to do what we wanted, no questions, we got time as a couple and fun as a family and time to cover chores.
I think - never judge a marriage until the youngest child has been in nursery for six months. You need a chance to get your energy back.
