<human>: Can you give me a shortened version of the text?

Some background: I have never cheated on my boyfriend before this. I believe fully that he has never cheated on me. We live together with my 4y/o son, and before this event were perfectly happy. I drink just about everyday, usually 6-8 beers in the evening before bed. 

The Story: So I made plans with good female friend from work to hang out two days ago. We had only hung out one time previous to this (outside of work) and had a great time. We have a good joking relationship and often make perv jokes towards one another, but only in good fun- nothing serious. This time we planned to chill at her house and have a few drink and play pool, then I was going to sober up and come home. Things did not go according to plan. 

Things started off fine, but I continued to drink shots and more beer and so forth. I ended up getting way, way too drunk, to the point of flashing in and out of what was happening and not being able to walk without falling. Regardless, I remember bits and pieces of making out with her, being naked, and being with her and her husband in their bed. At no point to I remember being unhappy about any of this, I feel I was a happy and willing participant at the time. Apparently during all this I called my boyfriend and slurred about not coming home that night. 

Next morning- I wake up on her couch, realize what had transpired, immediately left and drove home. As soon as I got home I woke my boyfriend up and told him I had made a mistake and- without to many details- what had happened. He was devastated. So was I. We cried, he left and came back. He decided he didn't want to leave me. At this point we are trying to be okay, but I can just feel his hurt and I want to die for what I have done. 

What can I do to fix this? How can I repair the damage I have done in our relationship?
<bot>: went to a female friends house, got wasted, had sex with her and her husband, told boyfriend, he stayed, now I want to fix this
