ML is trash point blank period

This whole story could be solved if the ML was likeable and smart. Instead he's such an asshole with no thoughts. Just jello in his head. How does he find fault with the FL ( her sa of the ML was wrong) when her actions were responses of his. He has consistently been irregular to her since childhood, yet she had to trust him when it came to his relationship with Lilly. She has never felt secure in their relationship and it's completely normal to hold doubt considering his indifference to him. I hate that people around him find this to be this "oh he's just a fool in love" character when he isnt. A fool in love would be observant, loving and affectionate. He hasn't demonstrated a fragmant of interest in her at all.
