Dear Lapoo I too am going through a bad time. My H started communicating with ow again. Throws everything out of whack for me. My emotions are up and down. I snooped. They tell you not to. Because it does bring heartache and pain if you find out they are still doing something wrong. That's where I'm at. It's tough. I am sure it was mentioned to read Divorce Remedy. That may help.
It is so very tough and the emotions are what get you. I too am resenting my H. We also talk but since I found out about recent contact I am not ML. I also am not sleeping with him right now. I myself may be separating due to this. But I found out in Feb and my H is not currently doing much to make the marriage work except talking and telling me how stressed he is due to work and life (he is in MLC). So perhaps read the book I mentioned and I know others on here will give you good advice.
