I'm just looking for some advice on how to navigate contact between my DC (15 months and almost 4) and DH. We had been together 17 years when he upped and left when DC2 was around 9 weeks old last year. I did a separate thread on this at the time so won't do a massive backstory.
There has been some involvement with Women's Aid and I was offered a space in a refuge earlier this year, but it was a very unpleasant and hostile environment and I ended up sleeping on my mum and sister's living room floor for a while. Fast forward to now, DC and I are very blessed to have our own house through social housing which we moved into in July.
Contact is random and sporadic. He will see them maybe once a fortnight, at my home or meet us at the park. DS1 will always say when it's time to leave "can daddy come to ours / can I go in daddy's car".
Will try to summarise as briefly as possible. ExH smokes weed and I had also previously found various packets of prescription painkillers in his bag, not his. He has various mental health issues. Recently was signed off work for a month after driving his company car and saying he wanted to speed down a motorway during a manic episode. Has told me he has urges to crash car into a tree. DS1 is on waiting list for assessment for ADHD/ASD and can be quite hyperactive, ExH says this makes him feel manic. He never asks to speak to them on phone or anything, forgot all of their vaccination appointments etc. He has missed almost all of DS2's life, he wouldn't know what size his clothes or nappies are for example. Just sees them randomly (normally arranged a day or two before), he takes loads of videos and selfies with them and then clears off.
Anyway, I'm borrowing an old phone of his as mine broke. He thought he'd wiped it but there were a few days worth of WhatsApp photos/videos and some call recordings. Aside from confirming he was having a fling with his employee 18 years his junior while I hadn't even finished bleeding from emergency c section, there are call recordings where he was casually saying to his colleague he'd taken "7 or 8 codeine tablets" the night before whilst drinking and smoking weed and how much fun it was, so recreationally. Also that he smoked weed in the park after work with girlfriend and then drove home to us. Aside from this there were days where we'd arranged to take boys places and he'd said he had left things at work etc but he was with his girlfriend. He is oblivious to the fact I've found all of this. I have backed up call recordings.
I just don't know how to navigate contact. I've worked in family law for years and have seen a former colleague for legal advice a couple of times, but cannot afford to pursue a Court application and would rather not go down that route if I can avoid it. Should I insist on supervised contact / a contact centre? Speak with a Health Visitor so at least it's on record? Every time he contacts me to see the boys I feel sick because I can't bear to be around him, but equally I obviously don't want them in his car. I am not looking to obstruct the children's relationship with their father, despite my concerns about his inconsistency and instability, I just want it to be in their best interests.
So sorry for the length / incoherent rambling, but would appreciate any advice.
