Driving Me Mental

I really don't know what to do with myself, whether to move out, whether to live with mum, whether I should mention to mum that I'm fed up with her lies and much much more. Basically as you know mum and my old step dad had split up and we moved out in February. Within a few weeks mum had started getting in contact with one of her old friends Paul. Yes that is great, mum is getting out again. Until I find out that mum is starting to flirt with Paul and vice versa. Paul may I add is engaged!! I don't mind the fact that mum is flirting with someone if it makes her happy. What I don't like though is that she may be breaking up a what was perfectly happy relationship which I know she hated when someone done that to her and my dad. I also hate the fact that my mum has given me two dates, this Saturday and a Monday that I have to be out of the house and I need to find somewhere to go. I hate the fact that I am being kicked out of my own home, its totally unfair and I'm not well enough to be just floating about the streets!! The last thing I hate (for now) is that my mum has lied to both me and my nan saying that she's having this "friend" (Paul) coming round as they have some business they need to discuss when I know for a fact that it isn't for this and its actually so that they can get up to know good. How do I know this you ask!? Because mum let her emails open and I next went on the laptop and also because my mum has left some disgusting photos on the computer that she failed to delete properly. So I wouldn't mind if mum wants people to come around but I would actually like to be told the truth. I think she forgets that I am an adult now and don't like being lied to! I am however going down to see the other half on the weekend as I don't want to be anywhere near the house to be treated like crap like I am. The best thing is the other half doesn't know that I am coming so it will be a huge suprise for her and she will love it (I hope) So my life right now is a little topsy turvy and I really haven't a clue of what to do for the best as I cant live like this. I move out the first time this started happening when I was 17 as I couldn't cope, sadly the difference between me then and me now is that now I am super poorly and have to admit I am scared to be living on my own!! So thats my little life for now, sorry its a little depressing!! TTFN XXXX
