Am I giving up to easily ?

Let me make it fast and short. I meet my bf online , dated 2 months everything was great. Then first disagreement he ghosted me for a month and half. I texted him to get some things back and we started dating again & it’s been like 6 months since.

He accidentally called me his ex girlfriend’s name , which we moved on from. Then he called me his cousin name while giving him a blowjob. Which he refused to talk about and we just moved on. Which I really didn’t. Now I can’t even talk to his cousin with out feeling weird or think about them spending so much time together which they do.

He told me for the last month I was going with him on a trip and had to choose which I gladly said yes I would go. I think that cousin is going. Then out of no where he said he got his ticket. And I said wasn’t I going with you. He said I figured you couldn’t go so he got it with out me. I said that’s very inconsiderate of you to not talk to me about it. We haven’t spoken since then and I just feel like this relationship has ran its course. I like him but it feels like he doesn’t actually want to be with me for the reasons mentioned above.

But it also feels like if I break up with him are those valid or could we fix this or am I giving up on the relationship over “silly” stuff. HELP LADIES.

Any advice
