Am I being too much ?

So, I have had a crush on this guy for a very long time. He broke up with his girlfriend like almost a year ago. As I got to know that I started advancing on him so we are dating for 5 months now. I have been very very patient with him. He cried missing his ex and I even consoled him.

I am trying to be understanding of his loss and even gave space. I asked if he wanted some more time so I could wait but he said it's not needed and he's over now. I was happy obviously but recently he has been reposting reels like yearning and waiting for them, saved and liked posts about exes. I believe I have treated him much nicely since we started dating but we just had a fight. I have been crying about the things he reposts, and I wished he would come to understand what I felt. But whenever we fight, instead of asking for forgiveness, he says , ' so should I just leave then ? ' I realized I made him too comfortable to disrespect me. So, I just broke up with him. I am very hurt. I felt like no matter how much I loved him, I was always a replacement . Haha sorry for rambling. I just wanted to pour my thoughts out.
