i miss being half of a couple more than i miss him... is that weird

this is going to sound awful but the thing im grieving the hardest isn't my marriage exactly. its being part of a unit. being a "we". the way ppl in the LS treated us as a duo, the way couples are kind of the centre of the universe at parties. now im a single woman in her 40s and i feel... invisible? or worse, suspicious. like other wives are wary of me now and i used to be the friendly neighbour wife. is this an identity thing more than a him thing? has anyone else felt this and how did you move thru it... im in auckland
