This is not going to stop if you continue to do the same thing.
If you rethink this and make healthy changes it may help, it may not.
However poorly conceived, why would he say he is doing this?
Do you mean make healthy changes in order for me to feel better and move on, or, try and make it work with him?
He has given me multiple reasons why he does this, mainly he says that he is afraid that I eventually will leave him, and that he has never felt genuine love from someone like he does from me, so he pushes me away saying he would rather regret losing the love of his life vs the pain of me leaving him one day. He also says he is worried he won't be enough for me, will fail me, is too damaged, too many issues, etc... He sometimes says he feels that I am better off without him, but that he realizes he can't live without me, so he pulls me back. I honestly felt that a lot of that was stuff that we could work through, until I discovered the online dating... that to me is where I really had to rethink this-and it is not the first time I have found him on there and i suspect it has went on for a long time.
