Thanks all for your continued posts! That is indeed an interesting link, thanks Feck. Believe me, there is a lot more going on behind the scenes than I am able to reveal here, especially given current situation. I did post on OW's FB page, that was a silly thing to do, but it was just factual rather than "inappropriate" and I held my hands up to that. I snapped, I shouldn't have done, but I did. I am only human after all and my life and my children's lives have been irrevocably changed by the decisions of two incredibly selfish individuals. It is in hand and will come to a conclusion I hope by the end of next month. I still have no idea how they came across my threads, neither do I care, but agree it is more likely that somebody has told them and I also know that very few people in RL know about my MN threads, it has always been my "safe haven" so I do have my suspicions. I have never had anything to hide. You can't post on forums like these and not understand the risk of being "discovered". However, I do think that if somebody is determined enough, no amount of "name changing" or anything else is going to stop them stalking you. It is just the irony of it given the accusations thrown in my direction

In terms of moving, I have no choice. There is no choice. There are very many reasons other than the behaviour of these two fuckwits. My husband has forced me into this position as he well knows. As a family, we are all agreed that it would be best for me to create distance (and that opinion also extends to my inlaws). My husband really ought to think long and hard about what he has done and WHY we have ended up in this position. It was all totally avoidable, he could at any time behaved honourably but he chose not to. This could have been over and done with in excess of a year ago. When he left, I asked him to give me a few months to pick myself up, get a job, get my son into nursery, market the house and he said no. He said no because he wanted to be able to lavish all the money he said he didn't have on OW and his "lifestyle" and that is exactly what he did. The truth is, he spent "our" money, our children's money on impressing somebody else and didn't give a flying fuck about what happened to us. I made him a perfectly reasonable 70/30 split offer in early 2014, with a small lump sum for me to be able to carry out necessary repairs on the house and an undertaking that I would sell the house within 2 years. He refused that too. The fact that I have had to go down the route I have is all down to his lack of co-operation. My husband has broken every single financial undertaking he has made, every single one, hence I need to find myself in a position where I can provide securely for my children on my own and I can't do that in this house with its' huge mortgage. He says he has "given me everything", he has given me nothing actually, I have never been in a worse financial position in my entire life and it's unforgiveable. We have not had mediation in terms of our DS, I can't see that being anything other than futile as it was with the finances and I don't expect him to mention it again. My DS is under a huge professional radar, everything is being dealt with. There is currently no contact order. However, there will be.
So, I have had a very relaxing Sunday...not! Now off for bedtime preps with DS...which takes a very long time, bless him. Thanks everybody, I really appreciate every single contribution!
