My GF broke up with me

We were dating for 1 year and 4 months me (26M) my ex (23F), 1 month ago she broke up with me.

I tried to find out why, she just stated that ist happy anymore and is uncertain of what shes feeling she said.

I only regret the 4 mistakes that I’ve done in this time of relationship:

1. First mistake was I didnt introduce her to my friends. Which raised kinda a red flag for her. But there is a thing, that she is very very shy around new people, I knew her very well, and once I did introduce her to 2 of my friends, everyting was fine, but afterwards when I asked her “How did u feel around my friends?” She replied “I didnt felt to well, cause they didn't take me into account that much, I felt marginalized.” From then I tried to control everything around me and her, she has this thinking that she will be judged wrong about new people around her, I tried to protect her. But sadly in the end she thought that I dont want to introduce her to my friends and she was thinking that I keep her only for sex and for my satisfaction. All I wanted was to protect her from bad judgements.

2. Second mistake was; she was very skeptical of me that I would cheat on her, I dont blame her attitude cause she had one relationship before me and didnt went that good, I didnt want to ask that much from her past though. Like I was saying, from her likely “paranoic” behaviour, she took my phone, and went through all my messages of course she didnt find anything, (except for 1 thing that we sorted it out and was my university colleague), she also looked at my tik tok likes and saw that I liked few tik-tok short videos of girls, I tried to explain that I was very sorry and she was developing security issues that she is no good for me, that she looks ugly and with big nose and so on. From that time I took all the blame and felt very sorry about what I did.

3. My 3rd mistake was. when we held arguments between us, I was the only one that ran away from fights. OFC I didnt dodge her for days or weeks, I just wanted to clear my mind and come back within 30 - 40 min to discuss. I did it several times, but the last time I was very sorry and told her that I will change and wanted I prove it with facts. She always tells me when I do this that "I always run from problems."

4. My 4th mistake. At some point in our relationship she asked if I look at porn movies when were apart. Ofc I told her the truth and said "yes". She kinda got upset and we discussed, she told me that "I didnt want to look at porn movies cause I respect you.". At that point I felt really bad about it and told her that "I wont make you feel like you don't deserve me, or betray you with somebody else." After a few weeks we went on vacation and she decided to look in my phone again. She opened tik-tok and went through my liked videos and saw a few tik-tok with girls. After that she got really upset and we went on a pretty bad fight, at some point we calmed down and she told me "Now I feel insecure and I dont think that I'm enough for you." and I told her that "I cannot deny that I see other people beautiful but that dosent mean that I love them or I want to betray you with them. If you did the same thing, that you like other men or looking at porn I wouldn't get that mad as long as you love me." When we arrived from our trip after a few weeks I saw a notificaiton tinder logo on top of her screen. I told her "Whats up with this notification, I know it's tinder cand I look into ?". She gave me her phone and it was my first time looking at her phone and it was tinder but she had a completely random photo, random name and random age. She told me that she installed it so that she can spy me if I got tinder. I was amazed... "Told her I don't want to betray you."

But she still dosent believe me and broke up with me on 15.OCT.2022.Told me that she felt distant.

I begged her that she is making a mistake, and stated that I still love her and wanted to get over this obstacles together, I cried in front of her when she gave me the news. It was a tough day.

She said that she will help me get over the pain and sorrow, but of course I told her she is making it worse. I told her that I dont want to talk to her anymore. And that I dont want to be in friend zone.

We kept seeing eachother. I tried to go to her university once, cause she was dodging me and was rescheduling the dates. I waited outside the uni, to talk to her. But she perceived me that I stalk her to see if she is seeing another guy. I told her that she was dodging me that's why I came up. Now she is scared that I'm stalking her... She said that "Now if u did this, I dont know what you're capable of, and I'm afraid."

Its this relationship salvageable ? I want to know how if it’s doable. (sry for my bad english, not my main language)
