People wed for some strange reasons today. I dated a female you couldn't tell me we weren't going to be married. Treated her well. In the end, she said she had out grown me. Then went back to dating the same losers she was with before me. I guess that was her comfort level.
You can't dictate what others may do or what they feel or will feel. You have to love because its what you are...what you do. Now if you you aren't receiving what you need from another then you can dictate your own actions and remove yourself.
