Should I end my 12yr marriage?

Intimacy is almost zero, guilt sex happens once in a while and it’s the most uncomfortable thing imaginable (it feels so wrong, she just lays there) Refuses to give blowjobs, I can barely touch/hug/kiss her without her pulling away, will not try new things, says no to lingerie and basically just flat out refuses, rejects, ignores or tells me NO. Wife says she has zero sex drive and just doesn’t want to. Marriage is perfect otherwise, occasional disputes, stress from the children etc but for the most part we’re great.

Tl;dr would you end a decades plus marriage over a lack of intimacy from your wife?
