You are a obviously a deeply caring and loving person, but having read everything you wrote I would have to advise you to break it off. This passage alone says it all I no longer feel like his girlfriend, I feel like his mother. I hate it!
He's lied to me, manipulated me, cheated on me, stole from me. He's broken my trust over and over and I can't even trust him to help me around the house, no trust with anything! I have never advised anyone to break up with someone before (I like to think people who love each other can work it out) but really this guy doesn't seem to have much invested in the relationship.
If you break up with him then perhaps he might get some perspective, and he may learn to stand on his own two feet. It may be that you two can have a happy ending, but it requires a change in him. One that he may well be unwilling to make.
If you love him then this is probably going to hurt no matter what you do. Best of luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
