I think every few days, because I think T truly does care, and sometimes we text.
But I realise it's less important for him than for me. I'm a client he cares about, one of many clients for him, past present and future. Whereas T is and always will be someone who had a huge impact on my life, and one of the people who cared the most about me in my whole life.
It's an imbalance, but I think I'm ok with it.
