Bro going to need to make a choice. Either marry and have 5 children with a woman who clearly loves you and accepts all parts of you and wants nothing but your happiness together or let her die from your own heartlessness and live with the shame and knowledge of what could have been. Certainly a tough decision.
This jackass must love waffles, pancakes or anything else you can endlessly flip flop. If he had a spine and wasn't an invertebrate jelly like substance, he would be firm with her, not giving these easy to misinterpret responses. Fuck this guy.
