He text another women during our argument...

Okay ladies...I need advice. My boyfriend and I will have our one year anniversary the day after Christmas..this past week has been super rocky. We had a small breakup because he accused me of calling him temperamental, narcissistic, and controlling....I never said those things to him. I think he went snooping through my phone and saw messages between me and my best friend. If I said those things it was because I was angry (I didnt mean it). So because of that he broke up with me and ignored me...even blocked my number. I had to swear on my bible that it’s not the way that I feel for us to get back together. Long story short...I went through his phone today because something didn’t seem right and I caught him sending a heart to a girl that he use to talk to. When I approached him about it he was extremely angry and threw past issues (from the beginning of the relationship in my face) he insisted that he was just angry and needed someone to talk to so that’s who he chose to reach out to. Apparently she gave him a bj before we got together and they had a “connection”....but he insists that they are only friends and is upset that I’m upset. The girl Didn’t respond to the heart.....I don’t know what to think..I just feel hurt. He feels like I shouldn’t feel hurt at all
