Please help me🙏

I came to Mumbai all the way from Odisha to pursue my MBA in May, 2023. My boyfriend used to work in one of the leading Indian commercial banks and was posted in Bhubaneswar, Odisha. It was a 10 yrs old relationship until I screwed up things. Initially when I moved to Mumbai, I was feeling very lonely as this was the first time I was away from my home and not living a sheltered life. In my college there was a guy (let's call him V) who took a lot of interest in me and we became friends eventually. I used to spend most of my time with him as he made me feel happy. During all these things I used to talk to my boyfriend almost every day but I had started feeling distant from him. He was preparing for CAT along with his job and was very occupied throughout the day. In the month of August,23, I was going with V in an auto and he suddenly approached me to kiss me. And it eventually happened. I was very confused about what I was doing. Then I just pretended that nothing had happened and I wanted to forget everything about that event. By September,23 I was feeling so distant from my boyfriend that I started doubting him although I never let him know about how I was feeling. He didn't know what was going on between me and V. He thought we were just friends. On October 23 , I and V decided to go to Pune for a 2 day trip. Because of financial constraints we had to book a single room and adjust accordingly. I didn't mind it because I was assured that there would be 2 separate beds and it was actually like that. In the room, I was lying in bed , trying to sleep. He approached me and asked me to hug him. I did. But from there on he just forced me to have sex with him and I was very scared. Eventually it happened and I was very sad about everything that has happened. I didn't want to but he just went on without listening to me. By this time I didn't have any courage to face my boyfriend as I had messed up everything but still I wanted to confront him. Me.V wanted me to break up and choose him over my boyfriend. V used to constantly nag me about this everyday and this used to drain my energy. Eventually I broke up with my boyfriend just 10 days before his CAT😭. I know I shouldn't have done this but if I wouldn't have done this, I think I could not survive. Even though I broke up with him, I didn't tell him about anything that has happened in the last couple of months. Now, I thought I would be with V and things will be sorted but no. Things had just started to go south. V used to abuse me verbally and physically. Most of the time I used to deny him for sex but then he used to put me under so much pressure that I had to do it. He used to be very manipulative and I didn't understand this. He was a sex addict and this was very late for me to realise. Eventually I had to break up with V in March for my mental sanity and in April I called my ex to confront him. He patiently listened to everything and gave me a lot of support. I want to get along with him but I don't know whether this is right for him or not. I know I am not a good person but do I deserve a second chance?
