When there are fluctuations, it is possible to ask to stay and radically change oneself — it is possible and good. Take steps towards, but you can not lose status (humiliate, creep).
Phrases that humiliate a man in the eyes of a woman (ascending):
- I want to help you! I am losing weight, doing exercises, reading the right books … What else do you need so that you agree to continue living with me?
- I’m ready for absolutely anything, as long as you stay with me!
Such phrases and such a position do not return the relationship and rather repel.
When a woman has decided to leave, asking (begging) her to stay is stupid.
If people competently part for a while, then many of them later converge. They converge if they cool down and understand that together, if not everything is fine, but better than separately. They do not converge if one side is persistently looking for meetings when the other side is not in the mood for it. Persecution is the end of a relationship.
