I do not believe I have ever posted to you, but I am a silent follower. I've been on these boards for over 8 years. I came here as a scared 27 year old who's husband just left her for his mistress. We had a 6 month old, conceived via IVF.
I tell you that, because although young, you are so mature and handling this like a champ. I just know if I made it, and I was a hot MESS (my D is 9 now, my ex married OW, and I deal with her as my D's stepmother), no matter what happens, you will be fine and you can always look to yourself with pride, just as your kids will.
