My son (20) seems to have moved his girlfriend into our house. From the day he introduced me to her back in April, she's spent every day and night here (with the exception of about 2). He works full-time and whilst he's at work, she'll spend the whole day in his room. That, alone, isn't the problem. The problem is that she's become a burden, both spatially and financially. She spends a lot of time in the bathroom doing her hair and make-up, which means that I'm often having to wait for her to finish before I can use my own bathroom. She's also been taking 2 showers a day - one in the morning and one in the evening (neither myself or my son have that many - we both have 1). Whilst she's having a shower, she often plays music from her phone too (which, to me, is an indication that she's gotten a little too cosy here). When my son returns from work, he'll cook an elaborate dinner for them both (he's a very good cook), and whilst he's sweating in the kitchen after a long day's work, she'll either be in his bedroom waiting to be handed a plate, or sat in the kitchen, watching him do all the work. In fact, this is the case with any household activity - he'll cook/clean/tidy whilst she'll just watch, usually whilst scrolling through her phone. She's also taken to swanning around the house in little shorts and belly tops. I've even see her put the heating and hot water on whilst my son is at work. She knows we're a family that struggles, financially, so to have her use our utilities this way is quite stressful. I've even caught her spitting in our garden whilst sat outside smoking. I just find that she's being quite disrespectful, now. AIBU to feel this way? His old girlfriend was really helpful and would always help him with household things. She was very respectful and kept her presence within the house quite small (she also spent most nights in her own home). This one doesn't seem to understand boundaries. One time she was ill with a cold and was coughing and sneezing quite freely around the house. As I have a young baby, I had to ask her to leave on that occasion and come back only when she is better - I didn't want my baby getting sick (he already has an autoimmune disorder which makes his immune system weak, which I explained to her). My son does give me a certain amount of his wage each month for his keep, but not enough to cover what's being used by the extra body to be honest. And, to be honest, no amount of money would make up for the inconvenience caused by her constant physical presence within the house.
Thing is, I'm afraid to bring this up to them because I know she's a nice girl who probably means well (although I do feel that she feels quite entitled to my son's treatment and the benefits of technically living with us - I think she feels she's a "catch" for my son). I just think she's young and naive to the impact of her presence.
AIBU to feel that my son's girlfriend's behaviour isn't really on?
