One more thing. I am beginning to consider not finalising the divorce. When I get the decree Nisi, I will have six weeks to decide whether to go ahead and apply for the decree absolute. This will mean that she won't be able to marry him so that he can stay in the country. He will then get deported as he is currently on bail pending deportation, but it may take a year or two. She will have to divorce me if she wants, but she might not as she is catholic (ironic I know!). However, given her present frame of mind, anything is possible! If she does file for divorce, I could then contest it on the grounds of her intention to marry OM who is likely to have negative influence on my children. The process could take another 4 or 5 yrs, by which time my youngest son will be 18, then she can do whatever she pleases. I am really not sure which course of action to take. Any advice please?
I would stall, delay, and stall some more. Legally.
Emotionally, and in every other way, I would protect myself. Talk to my attorney about trying to get a restraining order so OM can't come near my kids. Financially firewall myself so my wayward wife couldn't deplete my family's finances and assets. And emotionally, no more "dates". Time to detach and move on, and work on yourself and being the best dad you can possibly be. If she comes to her senses, you'll have some decisions to make about taking her back into your heart, but considering the circumstances I'd go straight to LRT.
