Iin, my sister's relationship normal?
My sister, aged 19, has left my family to be with a man in his late 40's. He was her football coach since she was 11. He seemed like a really nice guy and took me and my sister and his son lots of places and we went to his alot and his family and my family were good friends. He bought us things and made a real effort with me and my sister and would take us places and tell us not to tell our parents. When she was 13 my mum got a huge phone bill for my sisters phone. It turns out she had been texting him all day every day, even during school and late at night and they were speaking on the phone for hours every day too when we thought she was in bed sleeping or during the day anytime. When we confronted her she said she was texting and calling his son but my mum didn't believe her so confronted her football coach and he said he was just trying to be a good friend and listen to her and didn't know how to let her down etc. So my mum didn't think anything bad was happening but told him not to contact my sister again and to quit the football team. We thought that was the end of it. When my sister was 16 she got a job as an intern at the same place he works. When she was 18 she told us she was pregnant. She's never had a boyfriend and never really went out anywhere but she told us it was a boy in university that didn't want anything to do with her or the baby. We always had our suspicions it was her ex football coach. A few weeks ago we found out that it was him and that she had been seeing him in secret the whole time and has a different phone she uses for him. He has been married for over 20years and has two children, both older than my sister. She believes he was always going to leave his family for her (even though we think he only left when he knew we knew he was the dad) and he loves her and the baby even though the baby is now 10months old and he has hardly seen him and not provided any money. My sister says she hates us and loves him and doesn't understand why we cannot accept it. My sister thinks they have a normal, healthy relationship, am i missing something or looking at this wrong? Basically is it a normal relationship?
