Re: My heart is broken
You are where I was two years ago. I loved my husband so much and could not for understand why he moved out. I remained patient for almost a year because he said he was "on the fence" as to what to do. I now know he wasn't "on the fence"; he was stalling! While I was sitting at home crying my eyes out, he was partying to the max, traveling, and keeping company with many young women. He was having the time of his life! Talk about the cruelty of the situation! Friends and family tried many times to tell me to let it all go. Since he moved out and behaved as he did, then he was NOT undecided.
I find it odd your husband told your son he is going to see a lawyer. Why tell the child this? I guess he wanted you to know. Unfortunately, it's probably a good idea for you to see a lawyer too. You need to know exactly where you stand.
And there is nothing wrong with having hope. There's a very good book titled "Hope for the Separated" by Gary Chapman which might be helpful to you at this point. I realize it has heavy religious overtones and may not be for everyone. I found it to be helpful when I was newly separated though.
Hang in there!
