my long distance bf 22F cheated on me 22F

My long distance Bf cheated on me and apologised to me. Should I forgive him ?

We got together earlier last year in May 2022. I 22F met him on an online platform Bumble. He 22F looks innocent(not very good looking but acceptable) so i decided to give him a chance. I was moving overseas in July/August so I didn’t take this relationship very seriously at the start. He was possessive, outgoing and very dominant (both irl and in bed).
Before I fly off to US, I lost my passport and he was there for me consoling me. Then I started taking this relationship very seriously. Fast forward to November, we had a lot of fights in between and were fighting almost everyday in November especially around the exam period. We argued over him going to club many times before. I didn’t like how the place is, and if it’s something that I feel icky about I talked him into understanding where I’m coming from. He decided to go to club anyway after his exams while telling me he was going to assure me.
The first time on 29Nov he texted me throughout and I was really happy plus whenever he texted I just replied.
Then he came back the next day telling me that he didn’t really have fun because he kept texting me through out (btw during this time he threatened me with break ups but we never really broke up)
The next time he went was for a Zouk Out. (Singapore) I told him it’s okay to not text me throughout but he should send me pictures of who he went with. (it’s not because I don’t trust him but also because I wanted to see his friends
I love him, and obviously i’m curious about who his friends are etc etc)
Then he got annoyed at me.
Later on I found out that he cheated on me that day. It was someone from his Hall. (he stays in campus)
The scenario was him hugging her from the back or just touching her shoulders; her leaning on him. Then she kissed him. He kissed her back for a few secs (i don’t trust this info) but he walked away and started texting.

The first few days after he came over to new york, he was kinda wary and told me honestly that he was going to break up with me completely after the trip. He said this “let’s forget everything about our past and start afresh”. I thought he meant our fights. (we are both very stubborn)
Before he flew off I caught him telling one of his friends that korean girls are pretty etc. I confronted him about it and the topic went to “if one of your friend cheated would you tell his gf” and he said “if that was a one time incident and it might ruin the relationship I won’t” Then i felt very off?? because this man used to be sooooo against cheating and now he’s speaking for his “friend”.
I didn’t ask him anymore that day but when he flew back to Singapore I confronted him about this again. That’s when he admitted to me that he kissed someone else. He didn’t tell me the full scenario btw I had to find it out on my own. He told me that he really loved me when he spend more time with me in new york and was very sorry that he had to go through something so mean to find out he loves me.
My dad was a cheater so when I first found out I screamed and cried shouting “you’re just like my dad” and he got very mad at me. Hanging up his phone and everything.

Later on he told me that’s he cried a lot in nyc because he realised he loves me a lot and he hated what he had done to me.
Now I know that once a cheater always a cheater. I gave him another chance because he seemed sincere and he never had any kind of flirty text or shady texts ever. Even at the start of our relationship. He had always been a very good man (why I fell for him) rn i can’t really trust him and he understands the fact that i can’t trust him. He told me to give him a chance and start over because he realised it was the worst feeling on earth aka the cheating.

The problem is he doesn’t want to be reminded of this at all. But I can’t get over it. (NOT YET MAYBE LATER) I found out about this on 31 December and it hasn’t even been a week. I can’t talk to him about it because every time I talk about it he wants to kill himself and hates himself so much.

But from my pov; i was honestly burnt out back then too. What’s the worst part ? I was working for us so that we have money to spend tgt. This was so unfair to me. I feel suffocated, hurt and thought he did me really dirty. Even though this happened I still love him dearly. Do you think I made the right decision?

Ps i’m quite a difficult person, whiny, picky, clingy and low key like a baby

However, the days that he was in New York he was really sweet to me (VERY VERY PATIENT TO ME // very different from the previous him)
So has he really changed or is it all acting?? He’s those kind to tell you the truth no matter what (we had that argument a few times before because he was sooo truthful) but for the first time in his life he was scared to tell the truth because I might end our relationship.

TD;LR! cheater bf apologise and promise to change for the better
