Absolutely! They were together about 5 years, pretty serious, living together. Her mom died of cancer in 2016 and she was goin through a lot because of it, they were really, really close. Mouse kind of withdrew emotionally at that point and then sixteen months later her father died following an aneurysm. It was during that time, the 16 month period, that the affair started with her friend ~carah. She got pregnant and he told mouse about the cheating and she just immediately packed up her stuff and left him. She found out about 4 months after her dad died and she moved to Florida soon after but she's back now.
I am super open on pbs, but maybe Scott Eastwood? Or Nick Bateman? I imagine the cheating happened because she was emotionally withdrawn and probably their sex life took a nose dive.
