Unsure of what to think

I’m sorry for the long post! I’m just really unsure of what to think, and need some advice. 😔

The other day I get a text from my sister asking me if I dyed my hair. ( I have blonde hair ) That was a totally random question, so naturally I was confused, but I said no, because I haven’t, and asked her why she wanted to know. She told me that a friend of hers told her they thought they saw me and my husband at the gas station near our home last Monday but my hair was dark. I obviously said no because for one, my hair is blonde, and second, we didn’t go anywhere last Monday. I thought nothing else of the conversation.

Well this past weekend I was with my family, and my sister told me it was actually last Sunday that her friend told her they thought they saw me and my husband. My heart immediately sank because I was with my family all day that day and my husband was home alone.. so it definitely wasn’t me that her friend saw. To add, her friend has no idea where I live, so the fact that she named the exact street name that the gas station is located, which is the gas station we frequent because it is right by our house, only made me grow more concerned.

Anyway, that Sunday that my husband was home alone was a bit off too.. when I got home that night the garage door mysteriously wouldn’t open, which has never happened, and my husband wouldn’t answer his phone. I sat in the driveway for about 30 minutes before he finally opened the garage door. He claims the breaker blew which cause the garage door component to shut off. BUT, last year at our old house he locked me out of the house by unplugging the garage door, so I didn’t buy his story at all this time, but at the time I didn’t think much of it.. I just thought he was being petty because he was left at home all day.

So after putting all of the pieces together I decide I need to talk to my husband about what my sister told me. I asked him about it in a very calm manner, but he immediately got defensive and told me my sisters friend was stupid. He claims he got mad because he’s tired of people “trying to start shit,” and was upset that I’d even consider it to be a possibility. My husband has a history of emotionally cheating in the past and now I have no idea what to think or believe. I don’t know if I’m just in my own head or what. But I’ve been so sick over it for days.
