Not sure, but I think that time he broke up with her because he was even scared of being in a relationship that serious. They got back together, but it seems years have passed because I don’t think her sister was even pregnant yet when all that took place and last chapter they showed the baby, he appeared to be 2 or 3 years old. If that’s the case
I don’t blame her for wanting him to either commit to the next step or tell her where he stands. If he’s still afraid she needs to stop wasting her time/years with him.
Didn't this already happen before their first break up ?
Wasn't it because he didn't want to get married that they broke up in the first place?
