Hi guys right back again. As this is affecting the way I am I need some second opinions, I went on holiday a little while ago. I left my boyfriend at my mums house with my brother(which has bipolar) I got a message off him whilst I was out there saying he had a girl around and they just chilled. Didn't think much off it as I was on holiday. I come back he was acting so weird with me. Anyway 6 months have passed and my brother told my mum randomly one day he heard my boyfriend and this girl having sex. Off course I went mad confronted him and he said he didn't do it. That my brother was lying. I always had something at the back of my mind that I didn't like. A weird feeling but never really took much notice. Then went my mum told me I asked why no one had said anything. My family are compulsive liars and will do anything so I'm wrapped around there little finger. So now I'm stuck between my family and him. I don't know Who to believe. I sit up all night thinking about it I can't sleep eat or anything. Opinions would be great.
