This is exactly me & my life. Exactly. I don't believe that's how love is supposed to feel, and I continue to reject it. It's like you order a hamburger and get an old moldy tuna fish sandwich. I don't want that stinky old thing, I want a hamburger! LOL. Don't treat me like crap and think I'm going to like it - it's just not going to happen. That's not love. I don't treat other people like crap. I don't expect to be treated like a princess, but just a common average politeness is bare minimum to me.
My eldest - very similar situation. Drastic change, hates me now, says I'm to blame for everything wrong in the world, etc. It's devastating. Painful. Agonizing. I'm applying the serenity prayer, after a whole lot of tears. I'm trying to accept - this is just the way it is, and my eldest child, now an adult, has joined the rest of the world in simply not loving me. My parents - no love. Husbands, no love. Other family, friends - nothing. No one really cares. Painful, yes. But I learn to deal with it.
A glimmer of hope - sometimes, in a fascinating relationship, people lose themselves in the other person. Then over the years, the new wears off, and someone who was overwhelmed by the force of another's personality will sort of wake up, and say, Woah, that's not me! Hopefully that'll happen with your son, and he'll come around.
