I was scrolling through his IG and reading his posts just after Gemma died and you can tell he was absolutely devastated. I wonder if he moved on to try and block out the pain... perhaps a therapist would have been more helpful. I do believe he and Ethan deserve some happiness and if Derrina brings that, then that is good... BUT, I do think it is icky how fast he moved on. It is 4 years since Gemma passed and if he started dating Derrina last year or this year then I would not have much judgement. But he seemed to start dating her not long after Gemma died? The only person I can think of similar to this is Freckeld Fox (Emily Meyers). A young mormon blogger with 4 kids I think, her husband died from cancer and 3 months (?) later she was remarried. She was with her new husband for a few years, sold the family home she had with Martin and almost ended up homeless. She has now separated from her last husband and seems to have realised she never really processed Martin's grief, instead trying to block it out with the new man.
