Am I tripping


So we are married and have 5 kids together and dated at early ages and have things in our past ...... So about 2 months ago I was thinking about going out but I didn't but I did buy some condoms. So we moved into our apartment last month . And she goes threw my work bag and find them and I was 💯% honest with her about the situation and left them for her to take them. Today we get up have sex and she tells me go fuck her with a condom like she a different woman and that throw me off. Then tells me the box of condoms is open and only one is left. Them consistently ask we used these condoms and she say she don't know where they went ..... So what's really going on?
