Recently contracted HV2

So, I got my tests back today, I contracted hv2. I feel so stupid. I‘ve always been monogamous. I found out my last ex had cheating on me for a year; and I guess I picked up on some of his bad traits. I have had a handful of hook ups since then. Honestly, i regret all of them, and the most recent one most of all. I just feel like I was so stupid and just wish I could go back in time and say ”no.”
