Cole has some serious mental health issues. Low self esteem, extremely insecure. I'm not saying it's his fault, but those feelings can project themselves at the relationship- like it clearly did here.
There are times when you just gotta take a step back and work on yourself before putting your energy into a romantic relationship.
Though it seems like the last chapter Coles mentality has changed or is changing. Not gonna say whether I approve of them being together or not, I just hope things only go up from here for both of their sakes
