CC my H and yours, emotionally, sound very similar. My H is deeeeeep into replay but suffers great from depression and even has hints of withdrawal sometimes (I've messaged him twice this week and the second time he called my S18 to respond and I asked S to ask H to respond to me directly) He has suffered from depression for years as well. Forgetfulness has always been a bone of contention for us but I knew it was worse when one time my SIL commented that she keeps having to tell him the same stuff over and over again.
Not as young as you but still have a few years left in me:) that I would like to enjoy with a partner and like you a year is my time frame. I'll need to see some type of movement by then. In my sitch, though, my H is aggressively seeking D and will be signed, probably, by the year mark which, for me, will give me a push to move forward.
Feel what you need to feel.......we're all going through so much we don't need to feel guilt over our own emotions too.
Take care
