that sounds awful and it doesn’t seem like the comms between you are great.
it’s not just sex, it’s the lack of intimacy and contact. Not good.
is there a chance he is either gay or hiding a hefty porn addiction?
there’s a few choices here: you can drive a whole reset of the relationship comms (which may reveal unpleasant info, leading to divorce, or it may resolve things in an ideal world).
or you could choose to divorce without pushing for a resolution first
or you could choose to stay married, leave things as they are, and have other relationships for fulfillmemt
or do nothing and leave things as is (and you take the hit on how this makes you feel)
so, ok, not grest, but you do have choices.
best of luck and sympathy. It would be lousy for self esteem to be in this situation.
