Honestly did he love me or not?

I’ve been taking with this guy from the Navy for a year now, recently he came home for good in July and we got together. Ever since December of last year, things between us were amazing, we would snapchat day and night, we would text, and even got to the point where we would stay up until 3 in the morning talking on the phone. When he comes home, everything was perfect like it was out of a movie, we dated for a month and he breaks up with me because he felt like I was hiding something from him when in reality I wasn’t. He was the guy I’ve always wanted, so why would I hide something from him. We would go out, we had a good sex life, things were good but out of nowhere we break up after a month and I ask myself what I did wrong. Because for that month, everything was just they way I wanted it to be, I thought we would last forever. But Was it my fault that he broke up with me? Was it because I did something wrong? We still talked after we broke up and he told me he missed me, and tbh I missed him too, he was my bestfriend, the person I would go to for everything. We ended up being broken up for like 3-4 weeks before we got back together again. Things seemed different now, he wasn’t as sweet and loving as before. Yeah we would ride in the car together to school and he would hold my hand, he would kiss me, and he would hug me before I left to class, yet with time, I slowly noticed that he’s acting different. With another month going by leading to tonight that I am writing this, he breaks up with me. Telling me that the reason he broke up with me was because I always made everything about myself. He stopped having conversations with me, he never presented me to his family since July that he came home, he stopped being sweet to me. Everything just stopped. Currently my heart aches and wants him back, but this is the second time he leaves me. He promised me when we got back together that he wouldn’t do this again and here we are. In the end after all this, did he really love me like he said he did.?
