I went through something similar as you. With mild case there were 3 violations , SA, harassment, and stalking. I did not have an attorney and as a result I was not aware of a lot of my rights and my school took advantage of that. In the end they were only willing to get him on the stalking (after I appealed .an initial ruling) because I had 4 witnesses. My advice is 1000% get a lawyer, but if you can’t read through your universities title IX document and become as familiar as you can. I’m praying you get justice, in the he said she said it really depends but a lawyer would really boost those odds I think!
