OP, you said in your earlier posts that you have family and friends who have been listening to you and supporting you. Is there ANYBODY in your family that you could trust - mum, dad, brother, sister, aunt, whatever - to guide you through this in real life/real time?
I ask because when I was going through a heap of stuff, I really couldn't think straight. I was recounting some horrendous things that were happening to me and, if you'd heard me, you would have thought I was reading the news. I'd pretty much checked out of my cognitive thoughts. My point is that because I was in such a bad way and unable to think logically, I reached out to my cousin. He and I were close as young children and even though we're not even in the same country, he came over to help.
He listened, started making numbered lists, gently pointing out that the things I wanted were no longer on the table and were just not going to work - and took me through each of the numbered points, breaking them down into big tasks and small jobs. What I couldn't manage he did - and for all the things that I did, he was right there.
I barely remember that time now but I'll always remember how I felt when I saw him, the relief was unimaginable. Is there someone like that for you?
I think you're in the same 'frozen forehead', cold hands, slow movements - shock. I recognise the 'newsreader' style of your posts and I know the knee-jerk excuse-making that is very clear when you talk about your (ex) husband. I think you are still absolutely desperate to make your marriage work and you've seen this conversation this morning as a 'chink of light' and the start of getting it back on track.
You will set your recovery back some time if you don't come to terms with what is actually happening here. I think your ex is still reeling you in, still playing with you and is now using this tactic of taking your daughter with him as a 'nice thing' when it actually is more sinister than that. How do you know that he'll return her when you ask, not use her as leverage to get at you? He has form for that, he will do and say anything to get back at you, to hurt you and, like my ex, he is wanting to see just how far he can push you.
Please OP, think of somebody like my cousin that you could reach out to to help you with this. It's too much for you to cope with I think and you need somebody in your corner, making sure that whatever happens next is in YOUR best interests.
Do not agree to ANYTHING without speaking to your person-of-trust. This is the best advice that I can give you right now, that I would give my best friend.
