Sheree ismy world. I'm 36 years old, been married, have a degree and have a good career. Sheree is 54, (don't be put off) she ended a 30 year marriage to be with me and we've been together for about 30 months. We fought hard to get what we both wanted,. each other.
Now, I think she's outgrown me. She never tellsme she loves me, or even shows it. I think I rank about 4th or 5th on her priority list. I feelas though I'm constantly compeating for her attention and affection... she doesn't talk or say what's on her mind, if I tell her my concernes, she'll ask me "then why are you with me..??" if I tell her "it's because I love you" she raises her eyebrows and rolls her eyes as if to say... whatever. I love this girl... so god damn much... what on earth do I do, and what have I done to deserve being treated like a DOG??

If you've openly and honestly talked to her about your feelings and she brushes them off or ignores them, do you really think that you should remain in the relationship?

Relationships should be mutually beneficial to each party involved. She should think you're the best in the world and you should think she hung the moon.

When the compatibility isn't there, the relationship suffers.

I recommend trying one more time. Sit her down, tell her your concerns and fears, and see what happens. If she brushes you off... frankly, you deserve more than that.

I'm sorry that you're being ignored and made to feel like you're 4th or 5th place... that's not what you should be feeling.

18 years is a gap, but it is possible.
You sound very um, what's the word? Not sure, but she is your world and you need more from her. Is it possible that you are too needy for her at this time in her life?
My thoughts are that maybe she is having second thoughts or doubts about the decision she has made and maybe the life she left behind or possibly people she has hurt. There could be more to the story. If there are children are they all OK with the decision? Are there other people in her life that give her a difficult time about her decision?
So here's my thoughts, it's important to sit her down and get on the same page with her and let her know where you are at and what your feelings are. If you fought this hard to be together she must see a reason to be there, slow down a little, chat it out and allow her some time to respond.
