Hello Indu, I see you have posed two different questions. First about how upset you are because your h didn't take you to the anniversary party and now you are actively wondering about separation. I will deal with each separately. Regarding your initial upset and depression, I just wanted to tell you to cheer up. Please don't be upset and don't be depressed. You have not done anything wrong, you have not hurt anybody nor done a wrong action. So why should you lose your peace of mind? So first calm down and take a deep breath. What happened is not good, but it says more about your husband than about you. It's about him not you. So for you to take this to heart, and beat yourself over the head with means somehow you are blaming yourself for what happened. And that doesn't make sense does it? So dont be mad or upset. Try to create a space mentally in your mind, where you are able to see clearly that this is his mistake. Honestly speaking, Indu, this is how men are. In my life my brothers, male cousins, uncles and even my better half - all wonderful, intelligent, smart, good providers - and all of them, without fail, every once in a while, do something like this, something so stupid, so dumb, so thoughtless, so inconsiderate that I (or their wives and daughters) are left gasping in shock. I really don't know what happens to them every once in a while, does their brain shut off or what? And you know what, when confronted and their action clearly explained, without fail what they ALL say? Shamefacedly, shifting from one foot to the other, red faced, they all mutter. 'Sorry, I didn't THINK!' 'Oh, I didn't KNOW.' I think this is why all those books about men being from a different planet are so popular. You and I, in fact we women would never do such a thing, it is hard-wired in us. If there is a function, we cannot even dream of enjoying without our loved ones close by. But I don't know what happens to these men once in a while to make their rational brain function shut off. But in one form or the other, at some time or other, this kind of thing has happened to all of us, do rest assured. You are not unique. Your second question is whether you should separate. Honestly this is something you need to decide for yourself, but right now when you are extremely upset and emotional is not the right time. First I suggest you calm down and allow some time and distance between this event and your hurt to elapse. And I also suggest your defer the actual decision by a few months. In the meantime, try to do some things for yourself in terms of self renewal. Physical exercise, even going for a walk is great for clearing the brain. If you are religious, then doing a daily chant or listening to some weekly spiritual lectures can bring some mental peace. I personally found meditation very useful to understand what's going on with me. You can start with ten minutes a day. There are several threads here and an ongoing one where people log their input you can join. I suggest you keep a journal and immediately write down any insights you encounter. You will be amazed at what all deep thoughts and realizations come up. And I recommend you keep a gratitude journal for a few months. Write down 5 positive things that happened every night. I tried this last year during what felt like a dark dark time (pandemic and being shut in was driving me crazy) and it really really helped me realize I was magnifying the negatives while discounting the positives. Your own journey will be different but for sure what you realize will open your eyes. After a few months take stock and you yourself will know what you should do. Best wishes!
