I’m sorry your going through this, I’m going through it with my partner/ex now he tried committing suicide last time we split up & I took him back but he didn’t change he was spending 100 a day & I’ve had to kick him out he’s on his mums sofa.
I have found out that u can get him sectioned if u are the next of kin, I wasn’t married so it is down to my ex mum but she won’t cos she hasn’t lived it along as me, I hope u can help him it’s harder when it’s your son x
