The best thing you can do in the situation is focus on your own mental health and recovery. The more you lean into that the more you willl be able to take in on how to help him.
You are filled with shame, but you need to see that shame is a useless thing. It’s not an emotion it’s a belief, and it resides at the core of who you are. Guilt is an emotion that says "I feel bad for what I did" shame says "I am bad". And then all the things we do and think flow from believing you are bad, worthless, etc.
Shame blocks true connection because inherently you are self protective, you are hiding in a sense. And it makes you unable to experience their love because you can’t believe it could be real. It makes it hard to blow vulnerable. And this just grows a bigger and bigger void.
In many ways your anger towards him is conceived by this. You need him to love you so you can feel whole. But you need to feel whole so you can believe someone loves you.
And because you are so lost in your pain surrounding this, it makes him feel unseen in it. Your emotions stemming from your shame are so overwhelming you can’t let anything else in. Instead of feeling comforted, he is made to feel sorry for you because of your extreme lack emotional episodes. I am not saying that to shame you further but early after my dday, I learned that what was happening in our situation too.
A great book that helped me with that was "Rising Strong" by Brene Brown.
I commend you for not blaming your affair on a manic episode. I too was having a mental health crisis at the time of my affair- emotional exhaustion which is what they used to call a nervous breakdown. But recognizing that there are so many other factors that go into an affair is so important. Addressing as much of those factors is key.
The more you focus on your recovery over healing the relationship the more stable you will become. Think of this more as - how can I become the person I want to be? How to I learn to love myself so that the well of love that flows to others is pure? How can I best redeem myself to myself?
You are divinely loved and inherently worthy. You have made some terrible decisions, as have I. But by working on yourself you will begin to gain an understanding you don’t have to be defined by this forever. I think that what often can heal a relationship after infidelity is that growth will be evident to the other person, they will slowly begin to see you as reliable, and someone they can lean on. It’s not something you can fake, and it takes time to do it. It’s actions over words, and putting one foot in front of the other.
I know this is an extremely painful time you are at your lowest point of your life. I have been there. It was absolutely the worst thing to be inside my head. I wanted to die but I have kids and I wouldn’t do that to them or my husband, what an awful thing for them to have to live after. But the pain was deep, overwhelming and all consuming.
So the next part is going to feel silly or unhelpful. But when we learn to live ourselves we have to do that through actions as well. It’s how it’s built. So you need to do some things to help get yourself to a higher plain. Here are my recommendations:
1. Exercise. Take walks on nature. Your brain needs some happy chemicals and those two things can help stabilize your mood. I took up running even though I had never done it in my life. It gave me a sense of accomplishment and helped me burn off anxiety and stress.
2. Try to get in a good routine. Focus on eating and sleeping well.
3. Try to spend some time engaging in passions. When we can lose ourselves in something we enjoy we learn to let our minds rest. And it will become something you can tap into.
4. Make a gratitude practice. Spend 5-10 minutes a day thinking about at least three things that you are deeply grateful for. Really do a on why you love it this one is super hard to do at first and seems silly. But, studies show that in little as 21 days this starts to rewire your brain. You start looking for the hood so you have these things for your practice. And eventually you will notice that you experience these things more mindfully and they begin to spark joy for you.
5. Go to therapy, read, and learn that we shouldn’t believe all our thoughts. Everyone has thought distortion but people like you and I have it in greater quantities.
That’s enough to start. But in order to love a person, you do have to start with you. And I feel like my entire life that was just something people say. It’s not, it’s a real thing here. You were needing validation from this other person because you haven’t learned to give it to yourself. If you learn to give it to yourself, you will always have it.
The last thing- it’s the hardest thing- you have to loosen your grip on the outcome of this relationship. I don’t mean don’t try- you definitely should try. I mean recognize you are not in control of it, and that you should not try to control it. It creates desperation that blocks the healing that you need to do. It makes you want to do things to manipulate it. And I don’t mean manipulate it in an evil way, it’s a human thing to try and get it to go the way you want. Just know you can only control YOU. And gain the confidence that if you can’t work it out between you that you will eventually be okay and life will go on. You will find approaching it with any other attitude will hold you back from getting the very things you want.
I hope this helps. I know you are in a lot of pain. But life can and does get better eventually and when that happens you will emerge wiser, happier, more compassionate, and a great parter for someone.
