Hi everyone. I just got the shock of my life. I have three big kids aged 18, 21 & 23, the middle one is my daughter and the eldest is actually my husband's son, so her half brother. They all grew up close. Eldest has always been different and difficult, struggles with depression, dropped out of studies, never had a girlfriend before. He is about to turn 24 and we still help all 3 financially. Anyway a few weeks ago all crashed at our house after watching movies late instead of going to their share houses and college dorms. In the morning I realised the 21 year old and 24 year old slept together in spare room. My daughter seemed very subdued and told me she had a bad night and couldn't sleep. Now today she told me her brother was masturbating in the bed half the night. She didn't know what to do, couldn't figure out if he was awake or asleep, she cried and got up, switched on a lamp, made a noise, etc but it continued for hours. She slept about 45 minutes and then in the morning went to work with no sleep. She also said he slep at her house last week and borrowed some track pants from her to sleep in (although he knew he was going to sleep over he didn't bring his own). In the morning he handed them to her full of ehaculate and said he had an 'accident' in the night. His younger brother (18) was also sleeping there on the same bed. My daughter was furious and she told him to take them to the washing machine and if it ever happened again he would not be sleeping over again. I can't understand it. She is very upset but willing to forgive this behaviour. I mysef have washed his soaked bedding often but he moved out at 18 so I thought maybe a teenage thing he would outgrow. He is my step son. I am angry my daughter was exposed to this in my home. Does anyone have ANY suggestions? I'm thinking of trying to se a counsellor. By the way the 24 year old is always depressed and hinting at dark thoughts of suicide but won't take his meds. I'm so so tired of him.
