So I was dating a guy for 5 months and he was very serious about me at the beginning. He did a lot for me beyond the bare minimum. The thing is that i was still not over my ex and there was a comparison in my head all the time. That this guy wasn't like my ex and he is not for me. This lasted for 3 months of our relationship and maybe he felt that I wasn't invested. He is also training as a policeman and he didn't have a lot of free time to go out with his friends or me. We was going out only once in a week. Then I had an exam period and I became distant because I was studying all day and night and he showed respect. He only wanted to see me for an hour. When the exam period was over I was sure that I liked that person and I wanted to be with him. We spent a beautiful valentines day, and we were planning to go on a trip together. But first I went to a trip with my friends and maybe he felt like he is not my priority and I generally never talked to him about my feelings for him. We were just dating. When I was on that trip with my friends, he became distant in the chat and I was very worried, but I didn't do anything. I wanted to discuss that with him when I returned to my hometown, and one night he called me, and we talked very little, because I was eating with my friends. The last day of my trip he sent me a text and told me that it's better to break up because with our schedules we see each other once in a week and he has another whole year as a policeman trainee and that he is feeling that our relationship isn't so real, that we don't have communication and I agreed with him, but I tried to convince him that I want to change that and I am not the same person as the beginning of our relationship and if there was something in me it bothers him he should tell me earlier.He didn't listen to me, he just told me that he had made a decision even if it was wrong, because he doesn't feel fulfilled with our relationship and it isn't what he is looking for in his life right now. So, said that it is what it is then, nothing gonna change his decision now and I said goodbye. All this conversation was on instagram. I started crying, because he is a very good guy, but maybe he felt that I don't like him a lot and that there isn't something keeping him with me. I feel bad, I want him back, but what can I do now?
