kelela - Sounds like we are having a similar morning! I am so sorry. My crappy day yesterday started by looking on FB. I did it to myself looking at H's page because he had told me he was going to post a picture of the boys. I looked to see if he posted it and there was a comment from OW (and her stupid picture). My day went downhill from there. Stupid decision on my part. I just hate that I cant look at pictures of my own kids (my H is a professional photographer so he always gets the better pictures). If you are interested, there is a way to prevent your H's posts from appearing on your site. You can still remain friends and see his posts if you go to his page, but it just stops them from showing in your new feed.
I need to take this advice to heart but figured that writing it out to you may help myself. You don't know that H is never going to come back. I know that it feels that way now. But you never know whether things may change. Heck, if you asked any of us three years ago whether we would be on this website trying to save our marriage, none of us would have ever believed it. If things changed for the worse over a period of time, it does not mean that things cant change for the better over a period of time. We are both relatively new on this journey. It is so very hard. Please know that there are other people in your shoes walking the same journey. Know that you will get to a place of happiness on day and you will look back on this journey and be proud of what you have accomplished, regardless of where your H may be.
