Am I being crazy?

Sarah

So my husband and I got together about 4.5 years ago and before we got together he was with another girl for a year. They had sex and she broke up with him and then a month later he started dating me. The thing I’m still crazy about is the fact that they lost their virginity together and then he had sex with me and he’s the only person I’ve had sex with. I just hate that I wasn’t the one to lose my virginity with him and it makes me crazy. Am I just being a nut job?
