My boyfriend is grieving as his nan died , he wanted me there at the start for the first 2 months as his shoulder to cry on and now he’s in his anger stage and everything he feels gets taken out: deflected on me. I asked him if he needed space and he said yes so our relationship doesn’t get ruined from what he’s going through , I’m just finding it very hard and lonely and don’t recognise the person I’ve been with for the last 2 years, any advice ?
