Interesting problem.. I need help.

I'd wait for her to get the divorce then get together with her. You may feel like it's going to stress your life out because you'll feel guilty, but think about how your son will feel when he's old enough to realize that his parents are separated and aren't getting back together. You really should try to work things out with her if you love her (and you seem to).

Don't push her to get the divorce, but if she wants to, then just let it happen.
