GIRLS PLS HELP i feel humiliated

hi girlies, I hope you’re all well.

I’m going to try and make this short I do apologise if it isn’t. I had a bf, someone whom I love a lot, I have known him 4 years. I never slept with him because I wanted to save it however untill very recently we did, and he made me feel very comfortable. 2 days later I found out he was cheating on me :( he had a tinder account this whole time and somehow (like a sign from god) I saw his ig pw saved from a very long time ago on our chat and when I tried to log into his account it let me in and I saw that he had been messaging so many girls via dm on insta. I feel so HUMILATED, HURT, ANGRY and DISGUSTED at myself for letting this happen. When I confronted him he did NOT apologise instead he said he didn’t do anything wrong. Please can someone tell me what I should do, idk how to control my emotions, I tried to be brave but today I cried my eyes out infront of my manager. I am really upset hurt I can’t go out that much because I don’t have that many friends and all I want to do is sleep my emotions away which is very unhealthy, I also can’t tell my family because I’m not open with them. The boy very well knew how important my virginity meant to me. I feel so angry at myself I just don’t want to do anything any more :( 🥺
