I can only imagine what you are going through and my prayers and thoughts are with you. Stay strong! I think that you are doing the right thing and that putting your children first is the best thing you can do. You have been very patient and tolerant and it looks like you have hit your limit. Come here for inspiration. This place has been very important for me in getting me through my breakup with my XAB. I hope you derive inspiration and support from here, like I did and continue to do so on a daily basis.
