How to hold my tears?

[PandaWanda]

My husband has a long term affair - the OW is pushing for divorce, he resists and tells her he needs more time. To me he says that no matter what he will never leave me and he wants us to live together forever and that he still loves me. We live and sleep together (but no sex) and we are genuinly nice to each other, especially now, after I learned to do and say the right things.

But he is totally wrapped around her, obsessed even, sees her several times per day, constant talks on the phone. I am working the DB program and I know that I have a very good shot to live through the duration of this affair even if it takes a long time. The problem is that quite often I just cannot hold my tears -- they just appear by themselves, against my wishes, more often than I wish, in very undesirable moments. Sometimes I manage to run to another room or bathroom and not show it, but sometimes I am just not able to hold on and start to cry in the middle of the sentence.

Do you have any suggestiins how to get better control? I am holding up emotionally pretty good, but there are some hours that I can't do nothing else but just cry... What should I do?

thank you for your help,
