I need some advice please

I need some advice I’m going to try to keep it short. So there is this guy I’ve been knowing for a long time after a while get got to know each other everything was fine but, we have had our issues in the past which we talked about. We havent talked in a year and we started talking again during 4th of July. We talked about all the issues we had and everything was fine we would spend time together we would talk every day, we would send each other good morning paragraphs we would fact time a lot. We would cook for me for me his time and attention I never asked him for anything but his time and attention. His energy shifted from me he would go ours without talking to me, he would get home around 1am and then text me saying he was with his friends until 1 time we didn’t talk the whole day and he called me that night and had me on speaker and I’m like what’s going on and he hung up. So I called back we said hey best friend I hear a women in the background saying” best friend” saying it like she was so confused. Earlier that day I asked was he intimate with someone else he told me no something told me to ask him that bc I had a feeling but right after that night it all started making sense he was with someone and I didn’t even know so I hung up and texted him and said “ I knew it” bc I had a feeling. A few days later I texted him saying why you didn’t tell me and how could you do that to me ect. He never texted back which was fine I thought things would’ve been different this time I guess I was wrong
