At 18 I dated a stunted 33 yo bass player who was essentially 20? emotionally.
We're still very good friends after realizing that it was a horrible idea. He apologized to me recently. He's nearly 70 now. I'm 52. He said that after Me too he thought he'd been predatory. I told him bless his heart.
A 35yo as you describe is predatory. Assume the worst.
