Is it possible that me and my husband will end our 10 years marriage?

Being a metal horse with a wood ox, as a relationship, your relationship seems to be sort of incompatible because both of you have different personalities. Given that he is a wood ox, he provides stability and with you being a metal horse, you are very restless and like to go places. However, my common sense is screaming as I am reading your situation. It's telling me that if he is getting paranoid and accusing you of having a third party in the relationship then he could be feeling this way because he may have a third party hanging off of him while being in a relationship with you and he is just projecting his feelings onto you to try and cover it up. Regardless, I'd advise that you leave the relationship. If he is going to accuse you of this, think what else is he going to accuse you of?
