My ex might have given me what???

My cheating ex boyfriend of 2 years texted me last night and said he tested positive for HIV.... he said I should get tested and then blocked me. I don’t personally have the ability to go get tested and I’m scared that if I do it will be positive. What do I do? I’m scared and have no idea how to get tested. I’m a college student and have enough stress on my plate and honestly don’t want to have to deal with the possible disease my cheating ex boyfriends mistress has introduced into my life. If I have HIV can I have my own kids? What will change in my life... does anyone on here have it that can give me guidance? Please don’t lecture me about safe sex, I know I should have been safer but I never expected in a million years for the person I thought I was going to marry to cheat on me with some dirty girl he went to high school with. Please help me :(

How do I get tested?
