Awkward talk

So when I was 14 I was raped and my rapist took my virginity. I'm now 19 and married to my absolute best friend. Well he knows I was raped but I don't think I told him who it was. I knew the guy, was friends with him and my husband and I went grocery shopping a week or so ago and I seen that guy at the store.. he works there I guess. And I've been in such an upset mood since then. He keeps asking what's wrong but idk its hard for me to talk about it. I don't like keeping things from him it's just awkward for me to talk about it.
