Cupid, I can only suggest you give him loving thoughts (yes he maybe in denial or avoidance but he is unwell and deserves kindness). Be patient, his healing may take some time. Be understanding, he may be one of those blokes (like my family, loved ones) who struggle with identifying how they feel, what they want, how to communicate with loved ones, how to think about the future etc. he may also know exactly what he needs?? So respect must be given to his request for space.
most of all be kind to yourself: give yourself the time, friendships, support you need.
tell him: i know what you said, I respect your wishes, I will give you space, I still love you and if there is a way for us to be together I will be here.
hopefully he gets support from other blokes who may be kind and wise to get him into a good space to make good decisions.
sometimes some men just shut down, emotionally, verbally, physically (withdrawal into gaming, drinking or any other diversions). They need help but it has to come from someone or something (organisation etc) that he will open up to.
you both need some TLC. And...I hope things work out.
**I do want to say bullying is never ok and maybe you could talk to a trusted, non involved person who can give you some objective advice on the behaviour.
