DP and I have both been very stressed with work recently. Generally we try to support each other but it's piling up and I feel like I'm at breaking point. We're both grumpy and snappy and it's having a really bad effect on DD. Every time I hear him snap at her, I get annoyed at him and we bicker. Every time I snap at DD, he does the same to me. It's like we can both see each other fucking up but can't stop ourselves from doing it.
On a normal day, DP is a lovely man. But when he's tired and moody (which is most days recently), he's an absolute wanker. As am I. I feel terrible about the impact this is having on DD but don't know how to stop it.
Any advice would be much appreciated!
