Romance Interactions Help

Hello I need help. Every time my married sims use any interaction from the romance category they always reject and push the other sim away. I don't have the Lovestruck pack and I have moved all of my gameplay mods out to see if that will help and it does not. Is this a bug or have other simmers had this problem. I have checked and they are not siblings in the family tree, they have full relationship and romance bars, I make sure they are in a good mood. Every time I ask to discuss boundaries they always say they don't feel up to it. I just need advice because I can't do any romance interactions whether they are married or not. I have checked their sexual orientation. I don't know what this could be. I just got back into playing the sims and have updated all mods so I am stumped. Any advice welcomed thanks.
