Ive been cheating on my bf

I 22F have been cheating on my partner 22M with a guy i met months ago 36M. My boyfriend and I have been together for 2 years, we met sophomore year of college and our in our senior year now. We are in the same school, we get eachothers goals/job aspirations, he loves me for who I am and my mental illness. He supports me and truly loves me, which I've never experienced this unconditional love before (yes even from my family, i have issues, i know, blah working on it) But I feel like his mom at times, he always prioritizes work and career over me (which he has every right to at 22 and wanting to be successful) but I do often feel emotionally neglected and treated as an after thought and taken for granted. We live together we moved in in August. And idk I do love him but it feels like the safe love and like im in a very non passionate relationship.

I met a guy at a bar last may, turns out he works there (he wasnt working at the time I met him) and it was just conversations for like 2 months. He even says he never would of thought this wouldve happened. I had only been with 2 (now 3 ppl) and wanted to explore cause I felt all these things back then. I cut it off with the 36M immediately cause I had felt so guilty and wanted to be committed to my relationship. He reached out after like 3 months and basically ive been seeing him every couple of weeks now. When my bf was gone all summer we went on a few dates, we get eachother gifts, and we text everyday and have for 5/6months now

Im so sucked into it all, I cant see a way out. My current boyfriend is a good man, and he loves me but I cant let him. We have a lease, he talks about a future with me and I cant break his heart

Versus this rando, basically no future but we just have this spark. What do I do
