Dear alexa05:
I suppose it is convenient for him to sleep in her house, that he doesn’t have elsewhere to stay the night and/ or that a stay in a hotel costs money he doesn’t want to spend, plus he can be in the company of the dogs he loves. Not weird to me.
A man sleeping in his ex girlfriend/ wife’s house would make almost every woman uncomfortable, so I understand your discomfort with it. But as far as his motivation being possible convenience, saving money and spending time with his dogs, I don’t see these motivations as weird or as indications he things that you are “an idiot/fool”
Congratulations by the way for no longer being in a relationship with the man you posted about March of last year!
