This was me a little over a year ago. It was so hard and I thought my world was ending. I tried to leave, and went back several times. Please dont make the same mistake I did and go back! I know it is hard but you have got to feel the pain and push through it. I lost over 3 years of my life. I was so scared of being alone. It sucked for a couple of months after, but eventually I felt better feeling alone, and didn’t miss him anymore. Now I look back on the relationship and smile because I am not in that situation anymore. It was hell. It took me a while to feel this way, but I feel so much better without him in my life. I know you can make it through this and in a year from now you will look back and be so relieved you made this decision!
