Re: Brothers died
"It is better to be alone, than to be ill accompanied"....
I needed the repeat that quote over and over again when I went through my divorce.
You are the only person that can make yourself happy. There is no time line or clock for grief, and I suspect your boyfriend believes there is...obviously any empathy he was showing you was temporary and now his true colours are showing through again.
It takes courage to make a decision to do what is good and right for you, even if it hurts...the hurt will eventually go away and your strength will shine through.
My sincere condolences for your loss.
