My dearest friend died after a long illness in December last year. Her husband was devastated, as was I. During lockdown we have been messaging each other. It started with just checking that we were ok but then progressed to longer conversations. I found I was waiting for his texts every morning. Then we started to go for socially distanced walks and have grown closer. Yesterday we went for a meal and he told me that he had feelings for me. I realise I feel the same but I just feel so guilty about my friend. Is it too soon?
