Relationships

I have had quite a share of relationships and i must say that some were good and some not so much. But in every relationship there is one relationship that's most important - the one with oneself. In the attempt to be with someone you like you keep forgetting who you are and who you want to be. Somewhere down this road we realise that we have become someone we are not and thus start being incontented with our relationship. Relationships are complicated and need a lot of understanding but most of the time we see that only one partner seems to have taken over the reigns. Are relationships of equals just a myth or was it meant to be this way always ?
