The pig and the rat

Am a pig born 1959 sept 13.new partner is rat 1960 3 of March he is s lovely kind but no nonsense Man!
Been together 3 yrs we met I yr after my husband died!
Will we continue to remain happy and will he want to marry again (I am open to another marriage with him)?
We both make a lot of time for each other and always try to resolve relationship issues! We are loving couple and affectionate towards eachother. My concern also is that when he upsets me I go quiet ( I'm angry) for up to a day and become cold and of course this makes him upset! How can I change my behaviour is this a piggy trait and can you suggest what I might do to change! Yes I know it's up to me to do that I was hoping for another insight into the pig character flaws 😃😃
😃thanks for your time and your words of wisdom
