It has recently (yesterday) come to light that my exP has developed a cocaine habit that is far more frequent than first thought. I knew he did it occasionally (think maybe once a year at a stag do) and felt that although not ideal, it wasn't really anything I could bring up as an issue. He has now confessed to usage once a fortnight but I think he still in denial about this as some of his friends have told me it's actually more like twice a week.
He sees the kids at my place around 4 days a week and has done since we split. Not a situation I am happy with but he doesn't have a permanent base yet and lives out of a bag, flitting between here, his parents and a girl he is seeing who lives about 20 miles away. So it's the only way to see the kids. He says he's still paying off debts and can't afford a place yet but lives rent free (and has done for 4.5 years), earns over £50k and also smokes, drinks and eats a lot of shit, so I suspect the real problem is that if he has to pays any bills then he'll have to give up his champagne lifestyle. He hasn't paid towards the kids in 3 months due to changing jobs, but I'm assured this is temporary (and he did pay regularly for a couple of years).
I think he's in a bit of trouble but can only admit halfway because his mates were worried enough to have spoken to me. He's absolute furious with me for bringing this up. Says he was going to give it all up anyway but I'm not sure he can. Says I'm not trustworthy. I don't want to rip his kids away from him but now that I know the full extent of it, I'm very concerned indeed. He's affectionate with the kids but also snappy sometimes and constantly falling asleep and napping when he's here! He can be helpful too but I reckon that he surely must be unfit to parent if he's been out doing it the night before?! I'm really worried about where this is going.
Anything I can actually do about this? I can't make him quit obviously. He won't talk to me or open up to anyone. Keeps saying it's none of our business but I just think that as we share kids together, it kind of is! I'm the de facto parent anyway. I really don't know what to do. Do I have to take this legal? Are there any other routes?
Any help much appreciated...
