Questions

How long do guys keep nudes after they end a relationship? Does it depend how much they were into their ex? Does it depend if they get into a new relationship? Does it depend if the new girlfriend finds out? A lifetime?
How long are nudes saved for? And why would you keep them after you break up?
So many questions lol sorry. .

I reached out to my ex via Facebook not text and we talked for hours and then he suddenly said" here's my number just text me if you want"?
*does He actually want me to text him or could he had said that to not sound mean? We did end in bad terms when we broke up and he said he never wanted to see me and each of us to go our separate ways. Months after he started liking on instagram everything would post. Then he even followed me in my car once to see where i was headed when i was in his neighborhood. About 3 weeks ago he put up a song on Facebook and i 'liked it" and 2 weeks after i put up the following lyrics up and he also "liked" it. We have a long history together.
He has me confused.

Say a guy was trying to pursue a girl that was overweight who was otherwise minding her own business. He likes everything else about her except her weight. But when she decides to pay attention and end up liking the guy he proceeds agree to anything else but date her unless she lose the weight. He rejects her especially since he had falsely assumed overweight or obese people are easy sex and she didn't put out yet he's still interested but afraid of what it will do to his image if he dates an overweight person. She loses the weight and now he's more interested than before. Is she obligated to give him the time of day especially after she was humiliated for nothing?
