Hi Iraasuup,
I'm very sorry about your situation. Though I can't speak from personal experience exactly--at one point in my marriage I really wanted to try for a baby but my husband didn't want to at the time. He left for someone else and ironically, I don't have any kids but I hear he has at least two now.
I was wondering if, when you have the thoughts of "accidentally" becoming pregnant, which I think are perfectly normal in that most anyone in that situation would think of such things too, do you ever wonder if your husband would leave if you did indeed have a baby?
I'm not trying to be a dark cloud, I was just wondering if you ever have that fear. I've known two cases in which the woman "forgot" to take her birth control or "persuaded" a husband to go ahead and have a child when he clearly said he did not want kids. In the first case, they were not married and he left as soon as they found out she was pregnant. In addition to wanting a child, she had hoped the baby would bring them closer together, which, unfortunately, completely backfired.
In the second scenario, the couple was married and the wife "convinced" her husband to adopt a child--the husband began an affair with the child's babysitter, and promptly left her for this much younger woman.
I'm really sorry for what you're going through and certainly hope nothing worse happens.
