Her explanation is so weak, but also I understand where she's coming from. She doesn't want him to feel as lonely as she felt (even though she's clearly projecting). Also it makes a little more sense if you think about it from the baby's pov. As she grows she could get ostracized by having bisexual parents (which people will label as just gay). Even so girl go work in your own problems lol
I knew that present would come back to bite him in the ass. When he saw the money transfer he looked like he was about to cry. Good.
