Colin telling Pen she entrapped him really ruined his character for me

I understand he was hurt and I believe he was entitled to feel hurt and angry but I feel he was being needlessly cruel to Pen. He has seen how she is treated by her family and by society and the one time he doesn’t like what she has done he is just throws back at her the cruel words he overheard her mom say to her.

Meanwhile, Colin comes from a family that loves and supports him. Sure his family isn’t perfect, but his mother regularly checks in on him, his brothers take him out to celebrate his engagement, Kate and Anthony stay up to talk to him and see how he is, after his mother clearly was concerned enough about him to talk to them about it. We don’t see any of this same support towards Pen. And Colin, the one person who is supposed to support her accuses her of a planned entrapment. After he said that line I could not enjoy his character any longer. This was after the terrible brothel scenes that were a part of the characters decline in my eyes.

I will reiterate that I believe that Colin had a right to feel hurt and to take time to absorb that Pen is LW, and I believe Pen should have told him about it before they had sex. My criticism of Colin isn’t erasing some criticism I have of Pen, but I think Colin’s treatment of Pen after he found out about LW was petty and mean and went beyond feeling hurt. Penelope apologized for being LW and what she wrote, did Colin apologize for how he treated her once he found out?
