I found that when my oldest started school, it opened a whole new circle of friends up. How old are your little ones?
I go through stages of feeling lonely, despite being surrounded by people. I crave for that one best friend.. so, I know how you feel.
But, I did have someone, but she really let me down...(that's another thread!) And, I realised that it was wrong to put 'all my eggs in one basket'.
I no longer see this person, and I have worked really had in surrounding myself with some really nice people, who I now class as friends. But, I still miss having one really best friend, but to be honest, I would NEVER go back there again. It's much healthier to have a few good friends - than one best friend. You get too reliant on each other, and 'live in each other's pockets'.. and after a while, it can come quite controlling. So, work on building a few good friendships up.
Regarding the friends you mentioned, about the mind games.. I think that some people like to be needed and like everyone to 'know' that they are needed. My ex best friend was like that.. and it all ended in tears.
I felt that I was hiding the real me last year when we moved here... worried about alienating people.. but being too over the top or coming across as being too desperate to meet new friends. I stepped back a bit, and held myself back.... and saw what happened... and I have made some nice friendships with the women at the new school where my daughter goes. It's taken time, and I feel that I can be myself again. So, I do understand how you feel.
Like alot of friendships we have as mums.... NCT , pre-school and then school playground mums... we're all thrown together and the only real common ground we have is that we've 'all have sex within the same year.'!!!!!! 
But, there will be some women that you just really hit it off with and find you can talk too.. and be you.
