My step daughter stays with is every weekend. Her personal hygiene has always been poor, disgusting underwear, never brushing teeth etc. She arrived last night after a week at school and the smell was absolutely horrendous, she changed but didn’t shower and somehow the smell was worse. DP is a Disney dad who won’t say anything to either her or his ex for fear of causing upset. In the meantime I’m expected just to scoop up the clothes and wash them without passing comment. I bought her new tights, underwear and shirts to try and help the situation but unfortunately last night I failed to hold my tongue which ended up with me and her dad arguing. She had a bath in the end but this morning she’s put so much of some kind of fragrance on I’ve had to give one of my kids piriton which I don’t think is reasonable. I’m furious and lost my temper and now my husband has taken her out for the day to get her away from her awful step mother. Am I unreasonable to be annoyed?
