My son is 20 and seeing a girl who is 27 with 2 kids. He's not coming home and spends all his time at the pub, which she also seems to do despite having kids, she has a stepdad who lives with her who apparently looks after her kids while she's there. Her ex until recently has been living there too and has just left since she's got with my son. He's staying out all night and sometimes not coming home, not telling us, not eating, and I know he's 20 and an "adult" but I feel like he's being disrespectful of our family and putting his job and health at risk. We've always been close but I feel like I'm losing him. Last night we had a row about it and I've not seen him, he went to the pub before I got home from work and hasn't called or text. I'm really struggling with this whole change of demeanour and attitude, I'm not doing well with the whole situation and as my 1st child not experienced this before, some advise would be appreciated, I don't want to keep pushing and lose him completely
