Impact of Lack of Marital Relations?

My husband and I have not had marital relations in 2 1/2 years - (despite my requests/desires). I do not think he has gone outside of the marriage - however can this be considered constructive abandonment? He refuses to get testing/medical treatment - it has been a persistent issue in our marriage for over 11 years. (by the way, I’m a young attractive, healthy female - so it is not due to me)

Thanks,

His refusal to have relations with you is not enough to be considered constructive abandonment if he participates in the marriage otherwise (financial support, ect)
