He's not done anything to warrant it. He's kind, loving, caring, loyal, emotionally expressive but his words and actions are starting to leave me cold.
Not even because of how I feel about him - I love him - but because I can't accept that I'm am worthy of, or deserve, it.
When I think of things He's said about me or to me or things he's done for me, I feel like it is a cruel joke.
Even during sex, I now find my inner voice telling me that he preferred it with others or that it's a chore for him. Its making me want to withdraw. But it's hard because, if we don't have sex, I feel that it's because I'm repulsive to him or something equally unsavoury.
I no longer feel sexy or attractive 
This isn't the ick. I absolutely adore him, fancy him, love him and like him and would spend the rest of my life with him. If it weren't for the fact that I feel like this. He says this is forever and it's me or no one (were both older - he's late 50s).
It's got everything to do with how I feel about myself and nothing to do with how I feel about him.
When we're apart, I no longer have those lovely feelings of love, safety and security that I did have and he says he has. I feel cold, sad and undeserving. Like the whole world is laughing at me for being so arrogant as to think someone would want me.
If he were younger, with the dating choices of a younger man, would he still want me?
He says that, had we met when younger, he thinks we'd have been unbreakable and unstoppable and the only thing that isn't perfect is that we'll never be able to look back on a lifetime of memories together.
No one has ever loved me and I've never come close to feeling this way about anyone. But I can feel it falling apart.
