Is my relationship worth fighting for?

I have been dating my long distance boyfriend for a year and 1 week. Last week or so I had broken up with him because he had followed some girls on Instagram. Before he used to like pictures of girls in bikinis but I confronted him about it and he stopped I also asked him to stop following girls bc mostly everyone on his account is girls like hardly any boys and I'm the jealous type so seeing it hurts me. He stopped following girls for a long time but last week he started doing it again and I constantly being it up and we talk it out but it keeps happening. He followed his friends wife and it broke my heart so I broke up with him and then he goes and does the same exact thing that got us broken up in the first place. I saw him like a couple girls pic and started following a bunch of girls. I asked him why he did that and he said I did that on purpose bc I was hurt... So he basically hurt me on purpose. I met him when I was 15 and I'm about to be 17 in a few weeks he just turned 21. I don't know if I'm just too jealous and insecure. I once asked him if he can delete his account but he said "I will babe but what's the point i don't even go look on anyone's profile I just add them for followers, I'm loyal to you I love only you". I got some trust issues with him bc 3 months into our LDR he told me he still had feelings for his ex and how she's everything to him he can't explain how he feels. So that happens and we didn't talk for 2 days then when we finally talked he said I choose you I just still have leftover feelings for her but your the one I want to be with. His ex is his cousins wife's sisters daughter and they live with his cousin who he calls brother. They live like 3 houses down from him. Trusting him took everything out of me I constantly brought it up to him and I straight up said if you want to be with her you can bc I can't physically make you happy. That night was the first time he cried for me he told me everything and we talked about our future together. This guy is my best friend, my soulmate and my first love ❤️ we talked everyday throughout our whole relationship stayed otp 24 hours a day. I never felt so connected to anyone in my entire life we just clicked from the start. He is the most loyal significant other. Everytime, I jokingly ask him if he wants to have a 3 sum with another guy or girl he gets mad and super sad, he's like no amor you're only mine I'm not sharing you with anyone or anything. He doesn't even like me watching porn.. And I'm addicted to porn but I stopped watching it for him, he said why do you need that to watch that when you have me. He even cries when I try to leave him he won't let go of me 😭 I'm so fucken insecure about everything. So insecure that I never onced showed him my face on facetime and he only heard my voice maybe 4 times but it's just a hey baby I love you good morning. Every time he calls me I mute the call and I would just text my response back. Every now and then he would ask to hear my voice but I tell him I can't, to give me time, he understands and accepts it bc 1 year later.... He's still waiting. I know he loves me bc I also fucked up too, I kissed another guy this one time and he still forgave me. We are so honest with each other I tell him everything and he tells me everything even if it hurts. We never hide anything from each other. Now we are broken up we barely talk we just catch up with each other every night and see how each others day went. We don't sleep together otp like before, everything changed. We are kind of like strangers now bc we went from where we were to this... My petty self deleted him on Instagram but I still be lurking and looking at what he posts I even told him last night he said oh I didn't notice I don't even go on ig like that to check. I told him to delete all my pictures and my number and he said after you but we both can't seem to do it. We both want to just focus on ourselves right now, better ourselves for each other, well atleast that's what I'm trying to do. He says there's a high possibility we may get back together in the future but for rn he's just gonna do him. That honestly made me so happy to hear him say, he's not that close to anyone in his family he's the only child so he always says I'm all he's got. But I always tell him to spend time with them build a bond with his mom and call his dad and talk to him bc he's in another country and they barely talk. I just want him to be happy even if it's not with me bc this man deserves the world. I just love him so much he's currently otp sleeping rn but I miss him he's so far away yet so close😔❤️ he's the most important person in my life he impacted my life so much that without him I feel nothing. I need him in my life. Hes my first boyfriend and I made him talk to my parents and sisters, they all love him and ask for him so it hurts to hear his name come up everyday 😞 I never introduced any guy let alone girl to my family so this is a big deal for me. Nobody does it better than him. I was so hurt that I tried to move on but I just can't. No guy can treat me better than he has. I talked so many guys trying to find him in someone else but there's no one like him. All these boys and guys just want nudes and something temporary. I don't want that, I want what I've put my all into for a whole year. I want him I love him I want our future back. Idk what's going to happen from here he might end up finding someone else and that scares the living hell out of me. We used to talk 24/7 but now that we don't somebody else might start giving him the attention I used to. I apologize if this was all over the place but I've come so far in my relationship to just let it fade away. Tell me what you guys think. My heart knows what it wants but my mind is telling me differently.
