So sorry you are going through such a shity time. I dont know exactly how you feel, but i can sympathise. I asked my dh to leave last October (after years of emotional and verbal abuse) and it really did break my heart tearing apart my family. Only several weeks ago, i completely hit rock bottom, when he told me about OW of few months. A new level of heart break. Completely fell apart for a couple of weeks. Not eating or sleeping and feeling like even functioning at a very basic level was difficult. I had to resort to getting parents over several time as my emotional unsteadiness was too great. Plus i was completely confused by how awful this man had been to me during marraige and yet i was so hurt. I hated myself for feeling it.
Anyway, theres hope. The tears will get fewer. The self pity will get less. And you will gradually feel stronger. You MUST distract yourself. Keep busy. Push yourself to do things. I went a weeks holiday with dc and my parents. My problems didnt go, but i was away from my normal environment. Also, get angry! I don't mean shouting and violence of course, but start to look at this differently. Look whats hes done to you and your kids because he is selfish. Hes trying to be nice for his own conscience. Realise how ruthless he has been and let that harden your resolve to pick yourself up and move forwards in baby steps. And show him, that this will not break hou. and it wont....it will make you grow into a stronger person. You can do it! You will have good and bad days. let yourself have a cry when you really need to, even if its nipping to the bathroom, then dry your eyes and get back on with your day as best you can. Listen to uplifting and upbeat music. Especially songs about strong women or being wronged. It really helps, even just temporarily! Talk, talk, talk to your trusted frineds and family about how your feeling. Then change the subject and talk about other stuff. My work kept me sane. I had to function to work, or i didnt get paid. Dig deep for your childrens sake too. Exercise too-walk, swim, zumba, whatever you can do.
Spend littlest time with him possible. Dont chat or text on anything but kids. be business like is advice i was given. Keep away if he is there ( a lesson i am yet to practice, but my husband is manipulative and i dont trust him). Defriend on FB as that just messes with your head.
suggestions for your uni work??? Not sure. Its so hard to focus when in turmoil. You will have to make a decision on that one. Can you re sit? How will that impact you? Or can you take a few days and get through the work, just put your problems on hold, somehow !?!, and take the stance that you will not let him be the cause of your failure? Just do your best on this one.
Time to take control back, from him, and from your emotions which are ruling you right now. I am living proof that these feelings will subside. It will still hurt, but you'll be able to cope more and then you'll begin to smile and laugh again gradually. Youre at rock bottom, but there is only one way to go. Onwards and upwards. Someone told me "there is something better out there for you, but you are having to go through this rough phase in order to get there. " You will appreciate that one day. For now, take one day at a time.
Best wishes and take care xx
