idk ...things can and do go all sorts of ways. there are people who have married MULTIPLE times ...and they move on with life.
just from my experience: when i met my husband he confessed early on that he had a partner of 10 years and they lived together (not married). he always had time for me; we did so many things together that it did not cross my mind he could be in a relationship. after that confession i said under no circumstances would i carry on. he asked for two weeks ....during that phase he broke up with her and helped her move out. ultimately we got married but also divorced yikessss 😜😂
....so yeah you never know who you´re dealing with, really. and their motivations and reasonings. it could be deep love and affection or not. nobody is perfect ....
