I split with DH last July,we are currently going though a divorce,we were on good terms eventually,he's just started a career in the forces at 32,he's seen the children 6 times since July...there was an important family event on his side, my children wanted to go ,they didn't want to be without me as they still feel insecure,even though they are 13 and 11(i will do anything to support my children and make them feel secure)....I traveled 400 miles away with DH as he didn't have enough money to get there in his giant car,so we went in mine, I went with him and the children,stayed all day in a hotel whilst they were at said family event. I sent him a message at 10pm to say that i was off to bed and to be quiet when they came in(he had booked a family room!),at 11pm he asked for a lift back,as he had spent the money on booze,he was disrespectful and rude,and yes drunk,my children were outside whilst I tried to find them in a strange city..it took me an hour,by then he had called me 18 times,to remind me my kids were cold and tired and to get a move on....I found them and asked him to get out of the car,he was drunk and I didnt want an argument,he was disrespectful towards me, my DS ran off, i have never run so fast,we argued again,my DS got back in the car,Dh then locked me out and got into the drivers seat,DD opened the door and I sprawled myself in the car to get the key....Long story made a bit shorter,i was awoken by DS at 4:30am,his dad had been sick on his bed,(at 9am my DD was cleaning her step fathers vomit from the sink)....A long 9 hr and very painful journey home and he says he's now going for custody of my DS,stopping financial support,DH has a girlfriend and he spends every weekend with her and her children...................Ive booked an appointment with relate,for my children and I...what do i do next? Am I in the wrong?
