How do I help boost my boyfriend's self esteem?

Basin naa mo idea hahaha lately I notice super down kaayo sya because of his appearance, he's a freshgrad and currently working as a seafarer. And init ilang ubra and ni dark jud iya panit. Nawala jud iya confidence, this is my first time to see him like this! Last time we went on a date, I ask him to meet my parents and he refused kay mauwaw daw kaayo sya basin daw makaingon ako parents na "batig nawng" akong uyab, unya ra daw basta mubalik na iyang color.

Medyo ga worry ko kay concern jud kaayo sya sa iyang panit, sige sya sulti na mura daw mig kape gatas, gwapa daw kaayo iyang uyab unya siya bati daw kaayog nawng sa tanan. I keep telling him na dili jud tinuod na bati kay gwapo kaayo sya which is true, he became darker, moreno na sya daan pud and it suits him man uy. He is still the prettiest (and lami) man in my eyes charuth HAHSHSH bitaw ay huhu.
