Have we evolved to bond to women when staying in some form of relationship.

On surface level I know/assume that answer is yes and.it appears in posts on TRP.

I was just going to scratch it a bit more than surface but after entering phrase into G search I literally got slight gag like.when you try to date a whore and convice yourself its a good girl.

I appreciate any written input or scientific/medical sources on subject.

Thanks.
