I've been where you are too. Begging, taking responsibility for absolutely everything that went wrong, apologising for things I hadn't done, apologising for behaviour I hadn't done. I truly felt my heart was broken and I would never love someone else like that again. It absolutely killed me to think of him with someone else. He was emotionally abusive in the extreme and I believed him when he said it was all my fault. He would CUT UP MY CLOTHES to stop me going out without him!! I mean, wtf?!?! And I accepted this was my fault! It's laughable, it really is. But he's so charismatic that people fell over to spend time with him, so I genuinely thought that everything that went wrong was my fault!
It took me a long time to get over him. It happened in stages, like one week I would miss him less, two weeks down the line I needed him less, etc. I'm now 5 years on. Last year he got married and had a baby - that hit me hard, more so than I expected. I'm in a relationship with a lovely, kind, gentle man who I am head over heels in love with. A gradual falling in love, not a heady, passionate, quick way.
And you know what? I wouldn't get back with my ex if he was the last man on earth. He will never change, he will treat his wife the same way he treated me, to some extent or other. I actually feel repulsed by him.
You WILL get through this. Take it day by day, hour by hour if necessary. You'll find your self respect again, your dignity will re-appear and one day you will look at him and think - WTF?! He's not treating you like a decent person would - he lies, he's flaky, completely dismissive of your emotions.
I know it's heart-breakingly tough. I know that your mind is taking you to the darkest places. Something did help me - that was thinking what I would say to a friend who was in a relationship like that, or my dds. What advice would you give to them?
Take care of yourself and keep posting here xx
