That Exhausting Long Relationship

When I was 15, I met the love of my life. He is as old as me (18) and I have been in something like a serious relationship for 3 years. In the beginning, everything was wonderful - flowers, candy, theaters, cinemas, restaurants, etc. I was his princess, and he was everything to me, and that was evident in the fact that we were constantly together. When we argued, we quickly forgot about it and again found an excuse to see each other. Over the years, however, I feel that he increasingly resembles a lazy man who does not want to deal with his girlfriend. All he wants is to play video games, go out with his friends, and look for a reason to fight so he can just say, "If you don't like it, go away." I thought everyone was like that and that's why I still treat him, because I don't like typical bastards, and if nothing else, at least he's loyal. I guess most boys start liking it too, but I wonder why he's already behaving horribly with me after I haven't given him a reason and I always apologize for anything. At the school I'm in class, my shift coincided with that of the 12th and I met a very interesting boy. The first time I saw him playing guitar and just out of curiosity I decided to look for him on Facebook: D We became friends, once we were together on a trip from school and in the evening we were just the two and I really wanted him to give me a sign that he feels something for me (no that I was going to do something, I just wanted to feel some thrill and interest in me), but instead after explaining that I was in an exhausting relationship he gave me advice rather to talk to my friend. I expected this to push me away a little, but instead I started to fall in love a little. who knows all my relatives and with whom I have my first love memories or someone who will most likely understand and respect me and help me re-experience this love thrill in a new, more serious way. I will be grateful for my story to be published and to receive advice.
