My XH did the same thing Maika. We separated in late September but he wouldn’t even call it a separation until he hit me with a separation agreement in December. Since then, he has gone all in with OW. They bought a house together, went on a vacation, got engaged and are planning a wedding for next July. It would be comical if it weren’t so pathetic. Honestly, I think they rush things like this in order to justify their actions in blowing up their families and to avoid facing themselves. After all, if they don’t go all in, what was it all about anyway? No matter...we know this is about them and not about us. I know it $uck$ but it also helps us LBSs move on as well. She’s going ahead full speed. Eventually things will slow down and she will wake up one day with the same feelings of disillusionment that she did with you and maybe, just maybe, realize it wasn’t all about the other person. No matter. You will be long gone by then and enjoying a much better life. (((HUGS)))
