I'm a regular poster - some of you will recognise who I am. I don't want DH to read this so have namechanged in case he does.
I have posted before about DSS (16). Bit of background: DH and ex split long time ago (10 years). Ex left DH and moved in her partner whom she's had an affair with. Kicked DH out. He had to fight for access. Sees them the court stipulated amount and ex won't allow a second more. Despite DSS's age this has continued. She is very controlling and DSS is what you'd consider somehwat 'browbeaten'. Things everything his mother says is gospel. Starts every sentence with 'mum says...'. Shows no signs of growing up emotionally. To me, I honestly can't see that he has developed much emotionally at all in all these years.
Behaviours are very emotionally detached from life. Doesn't seem to get much joy out of anything. Spends no free time with friends (although he does have friends). Hobbies chosen by his mother etc.
Recently made the statement that he 'never misses anybody'.
DSS2 is very different, very caring etc and speaks out against his mother's mantras.
Anyway I am finally getting to the point of this thread, bear with me. Yesterday DSS1's Spanish homework was on the dining table. I was interested to see what standard he was at (he does well at school and gets 'A's in languages). I read a paragraph where it said "There are 5 people in my family - my mother X and my father X.... ETC". I did a double take, because instead of DH's name, he'd put his mother's partner's name
. And described his siblings excluding DS (but including his half-brother in his mother's house). He didn't mention DH at all 
I am so upset for DH. And unfortunately I blurted this out to DH in my shock, which I probably shouldn't have done.
DSS's standard of language is high. I don't see why he couldn't have put the word for 'step-father' or whatever. I'm assuming that in a class of 30 there will a good number with various household relatinships away from the norm, and that these will be taught.
Feel so sad for DH
