Hey OP - I did read most of this thread and also saw you posted last week and were feeling really low.
Really sorry you are going through all this and I also wonder if your DH was contributing to some of your self-esteem and depression issues.
You pointed out some unpleasant behaviours that he was doing, and I know from experience that "coldness" and "unkindness", although they may seem small, can also hint at someone being emotionally abusive. Raging over nothing is a red flag, in particular. So is coldness towards your feelings, and not talking, also known as stonewalling.
You don't need to think about the long road of leaving if that seems overwhelming right now, but I do suggest you contact Women's Aid or a local outreach group as you may be in an emotionally abusive relationship and this could be contributing to you feeling really down.
Once you get validation that this may be going on, you will start to regain your sense of self and know that there is nothing wrong with you; you are not unloveable, lazy etc, you are just with someone unpleasant, and anyone in your situation would feel the same way.
Small doses of unkindness, not seeming to care or doing caring things like making a cup of tea etc, although they don't seem as massive or obvious as physical abuse, over time become wearing, and will run you down. You might even feel worse because it's hard to pinpont and seems like 'nothing'.
I agree that in normal situations, people are responsible for their mental health and well-being but you may be in an abusive relationship and this can be hard to spot, but you will have a general sense that something is 'off' and a horrible feeling of not being properly loved or respected.
Please call Women's Aid - you won't be overreacting.
