The only complaints I have are that the lead couple didn't really have much chemistry. I felt like the ml was holding the relationship together that the fl never really committed to the relationship. Like she had one foot in and one foot out. He seemed to be the only one initiating the relationship and it felt like she was going along with it.
I also didn't like her wardrobe. I understand they were going for a look where she is older than him but his mother dressed better than her. And the outfits his mother wore were more stylish than her marmish clothes.
And why didn't she actually try to get her son back? She said she would but when it came down to it, she just had visitations with him.
