You sound like you are handling everything well. I know it wasn't easy to hear that but from what you say about your x's response, it doesn't surprise me.
These MLCers run when they feel trapped. Think about it? All the cliche phrases we hear.."I feel like a hamster on a wheel, I don't know who I am anymore, I am not where I want to be in my life" and on and on.
Now, I can just imagine the WORST thing these guys want to hear is that "I am pregnant". Especially, if that is heard from someone they are not getting along nor see a future with..
Yikes.
As for you, young lady, you have come such a long way. Just reading your post today made me feel so proud!
I think it is very wise of you to leave this all alone. And, it wouldn't surprise me a bit if you know who comes knocking on your door one of these days..Be prepared..
Keep us posted on how you are doing and let me know what else is knew in the world of "whitelight!"
