Hello everyone and thankyou all so much for your replies and words of support and comfort. I'm sorry that I kind of posted and ran but I've just been in the middle of so much stuff for the last couple of days.
I am in such turmoil and I can't maintain one thought with much certainty in my decision for more than a few hours. I'm afraid to say that I'm back and forth with 'leave' and 'try'. Though I know I am likely to be being foolish.
My family are hopeless and are only willing to support me if I leave him which is not at all helpful tbh. My sis let rip that if I 'tried' then my oh could not come to her house or see her children, because she didn't want to 'risk it'. As in she thinks that my oh is a danger to her children. Mostly because she has vey strong feelings about internet pornography which my husband has been addicted to for most of his adult life. But as far as I'm aware it is all adult porn, and nothing illegal. It is a genuine addiction, he has nearly lost two jobs because of it.
It is so hurtful to be told by my sis he would be a risk because it makes me feel that I am putting my DS at risk and I know it is not the case.
Sadly her input on this last night completely tipped me over the edge and I found myself with a pack of tramadol and a wild idea in my head. Thank the Lord for the Samaritans, they really do an amazing job.
So I'm now in a better psychological place today. I expect that oh will stay moved out and we will need to make some longer term plans about how that is going to work.
I intend to see my GP to get some time off work just to get some breathing space for a couple of weeks, and also and STD screen to be sure (I'd been thinking of it too math).
We are at Relate together and I sort of feel I need to work that part of the process through to help me decide what I want to do. I hope I don't end up with a worn out tshirt too sububophobe.
So that is kind of where I am and I would appreciate being able to come back to talk to you all. I've got very supportive friends (one who is now disposing of said tramadol) and I think I'll be ok, it is just going to take a while.
Sorry for all the typos but I cannot be arsed to go back through it all.
P.S stubbornhubby you are a fuckwit. Thanks to everyone else. I used that expression to explain that they weren't just my friends, they were his friends too, fuck off and be 'helpful' somewhere else.
