Is my boyfriend an interbred or something
Well I've been with my boyfriend a year and 4 months and I love him but I'm concerned about his relationship with his family. Him and his family are close but my boyfriend who is 17 seems 2 close 2 his sister who is 19 and his niece who is 3. His sister has her own house bt comes up everyday to his familys house and him and his sister play fight like get on top of each other and stuff, me and a few friends say that its weird because there 17 and 19 and the way they play fight is like a 'flirty way'. He often babysits for his sister and once when I came around his niece who is a little girl was watching tele naked and I came and sat next to my boyfriend and he kissed me and he put my hand on his '''' and it was on hard I find that weird he said it was because he was kissing me but at the bk of mind it made me wonder because it don't normally pop up like that. It makes me sick and worried if he is some kind of interbred. Sometimes when his niece stays over she stays in his bed even though she has got a bedroom which I think is inappropriate as she is a 3 year old girl and he is a 17 year old lad. I love him and thought it was just me but my mates comment on it 2. am I thinking too much into it? Is it normal? What should I do? What do you reckon?
