Bless your heart....

You should, I think, leave. His actions speak to a lack of maturity, a lack of trust, and a presence of malice. His actions to you were premeditated in an effort to cause you pain. That's very, very cold. You deserve much better than him. I know leaving a relationship like this hurts, especially when you've shared something like your first time, but this is something that is both awful for him to do and a major red flag. This says, to me, that his response to major "issues" like the one he perceived isn't to communicate with you but to employ the flawed rationale of "two wrongs make a right." That's not a stable basis for a long term relationship.

I'm so sorry. Please know you are in my prayers.

Hugs,
Harley
