Have you both communicated your goals with the separation? Is the intent to take some space and get perspective in order to find your way back to each other? Are you guys dating other people during this time? Do you have a general time frame of the separation? My husband and I have been going through a separation with the intent of staying married and we'll date each other, but not seeing other people at all, if this counts as a success story. We're still working on it.
Depends on how long and if there are other women involved. If they get attention from new women no he will not but if he gets lonely yes. They all come back but depends how long for that they stay
