I’d like to think by 7 months I’d have already had serious conversations. Obviously depending on the reasons given and how willing they were to try and work through it would be a major factor but I’d be thinking of ending the relationship.
As others said ,we'd be talking about it and finding out why well before that.
Life happens ,illness ,loss of libido,people lose their mojos.
It's what you do about it that matters ie try to work on it
I definitely wouldn’t be adding to the problem by going on any kind of site with the aim to cheat ..I would have a conversation if nothing got resolved then I would walk away .Life’s to short to be miserable..x
